Thats not true anymore, the US$ has increased the money supply around 37% in december, since there is no one not using the Dollar, we can expect inflation in commodities, basic means of living, rents, gold, Bitcoin.
There is now so much money in Bitcoin and︀ the devs made it so unusable as "peer2peer" electronic cash that I would still say︁ just buy in a few bucks every month and hodl. For actually using cryptocurrency there︂ are better ways, as store of value every proof of work coin with a marketcap︃ within the top 10 you can´t really do anything wrong imo. At least not more︄ wrong then go into the stock market which is a total casino at this point,︅ its so rediculously obvious it should be to see for everyone. But we aren´t there,︆ "nobody" of the regular stock market daytraiders got it, besides a few very big companies.︇ It will have a crash, but I don´t think it won´t come back since fiat︈ is garbage worth at this point you loose money every day you have it on︉ your bank account. No matter where you live.
