In my case I see the future in cryptocurrencies and I think it is the best way to invest or multiply at this time, although I do not know what will happen in a few years. I do not think that all the crypto currencies end up collapsing, but I agree that the vast majority will end up doing it. I think it is still too early to know which ones will continue and which ones will disappear, but what I observe is that many people keep buying in search of easy and fast money. This, as a rule, usually does not have long-term positive consequences. You must choose well which is the best altcoin for you.
