Well to be honest, I think the article angles towards all the uncertainty that is around cryptocurrencies. I aggree to the fact, that the risk of loosing fundings are definately there - but it is also risky to invest in the stock marked. I am sure a lot of people can aggree to that. What people have to remember, is that legislation only provides you with one type of safety - revenge! The state punishes the abuser - but does not refund anything. The idealistic approach to cryptocurrencies (the serious ones) is decentralization and democracy scattered around people - and not as a representative democracy - more like a direct democracy which is possible with the blockchain technology. However there are still a lot of problems and challenges that needs to be solved. The idea of tokens have indeed attracted criminals and other people from the so called dark side for privacy reasons, but it is actually no different from using cash or gold or similar values that are held by the individual and outside governmental knowledge. It is the use of any valuable that determines if it is a bad or a good. Some other challenges and problems are continuity during times of crisis and so on. The internet has become just as important a part of the worlds infrastructure as mail and radiotelegraph used to be. And therefore states tend to want to control it, maintain it and make sure it works. But at the same time, states want to decide how to use it, which people of the internet tries to resist. In my mind there is no doubt, that blockchain technology will become a bigger and bigger part of the international and national infrastructure as the technology developes more and more. And it will be more and more difficult for states to control it. Until that is accepted broad by governments - which I believe signs are already shown - there is a risk of loosing money on cryptocurrencies because exchange between FIAT and cryptocurrencies might be closed on the official platforms - leaving people to exchange their cryptovalues to FIAT on the streets physically p2p - which of course will devaluate cryptocurrencies broadly. I do not foresee that though some limitations in withdrawals might be imposed - I think the technology is here to stay, and it will grow. That said, it might not be BTC or ETH or any of the trending currencies that end up being the preferred one. So in short terms it is all about your own stomic feeling. But as long as you don't invest more than you are willing to loose - and scatter it amongst the currencies that seem strong and well supported in their communities - you could get a bit more interest of your investments than on the stock marked i believe. I wish you luck.
