They have had terrible transparency since the hack and it’s suspected that they might be the ones buying their tokens back at a cheaper price in order to get out of having to pay back their debts. Without transparency this all just seems like a huge scam. Why are people using them to continue to buy bitcoin?
Edit: Follow up question, do people know if they are taking fees on the trading of their debt token? That would be absolutely ridiculous if they are!

Economist and best-selling author Harry S. Dent Jr., returns with positive comments on the PMs sector; the gold market follows the commodities cycle, which continues to advance. Every investor should allocate 5-10% gold / silver to to their portfolio to improve investment diversification. In addition, PMs bargain hunting is in vogue, amid news of huge losses related to security issues in the Bitcoin encryption methodology. The positive trend in US equities is directly correlated to negative rates – investors have few options other than chasing risk to boost expected returns. Nevertheless, our guest suggests that weakening economic conditions will persist, which could lead to a new round of QE4 and subsequent inflation.
Scaling-wise, the Bitcoin Core developers are mainly focused on:
Both are very good ideas which will probably be essential to Bitcoin’s long-term scaling. However, some people seem to be extremely concerned that fees could increase too quickly, and that the above solutions may be too slow in becoming widely useful. As I have previously mentioned, there are several options for quick scaling beyond SegWit or Lightning. I will outline a fairly simple one here, which will work on the Bitcoin network as it exists now. For those concerned about this issue, I recommend working on creating something like this.
The idea is to make a federated sidechain with an unlimited block size, and rely on a certain amount of centralization within that sidechain to increase efficiency. This is the same way that Blockstream’s Liquid cryptocurrency works, which is intended for high-volume settlement between banks.
With federated peg, a fixed set of centralized entities are designated as “signers” (aka “functionaries”). These are the only entities which need to run full nodes, so scaling is way easier: just buy super-beefy servers for all of them. Everyone else just needs to download the sidechain block headers, their own transactions, and the needed Merkle branches. Also, confirmations are near-instant because there is no PoW mining. If the signers are all independent (ie. they won’t collude) and in different countries, then this arrangement can be quite secure, and arguably even more decentralized than when lightweight nodes trust the highly-centralized Bitcoin miners. The Tor network works similarly: the entire Tor network is administered by about 6 directory authorities run by independent organizations in separate countries. Obviously, this centralized arrangement would be totally unacceptable for Bitcoin as a whole, but I think that it’s reasonable in this context.
Blockstream has a framework for building your own federated 2-way-peg sidechain that will work with today’s Bitcoin network: https://www.elementsproject.org/sidechains/creating-your-own.html Take that code, make a few adjustments for high volume (see the end of this post), and run with it. The code/instructions above creates a sidechain with only 1 signer — for security, you’d want to have multiple signers (maybe 10-20) in a production network. You could copy code from Elements Alpha for this.
From an end-user perspective: Wallets supporting the sidechain would have two separate balances, which can be thought of as “checking” and “savings”. The savings part would be BTC balances exactly as now. The checking part would be BTC in the sidechain. BitPay etc. would show just one address, but would listen for transactions on both the Bitcoin network and the sidechain. Users would periodically move BTC from their savings to checking. Because the checking side is centralized and therefore less secure, I envision people generally never having a balance of more than $1000 or so in their checking balance — if a transaction is more than a few hundred dollars, it’s better to do it on the Bitcoin network directly.
It’s like having a high-security Swiss bank account which only allows wire transfers (Bitcoin network) plus a less-secure checking account which has a debit card (sidechain).
Adjustments for higher volume:
Additionally, it would be possible to add anonymity features to the sidechain (eg. confidential transactions). But I’m thinking here about something that could be done pretty quickly, so that’s not essential.
Elements Alpha (already running) and Rootstock (apparently soon to be released) offer many of these same advantages, but they’re not really focused on high volume or close integration with Bitcoin transactions, so I think it’d be better to create a dedicated sidechain for this.
Since much of the code is already written, I think that a dedicated team could probably have this up and running in a month or two.
