Cryptocurrencies are not down, the market is just stabilizing. The crypto market went through a stage in the beginning where a large percentage of the "investors" were simply people wanting to cash in on the fad. This caused cryptocurrency prices (mainly BTC) to get to unrealistic, and unsustainable levels. Now that a majority of the bandwagon investors are starting to leave, the price is entering a more normal sustainable state. I suspect it will take many more years for this market to be as sustainable and trustworthy as the forex market, but it will eventually happen. Crypto is here to stay imo.
