How long you can hold bitcoin and altcoin? I have tired with many my assets altcoin like ethereum, litecoin, atom and bitcoin cash price going down. What better have I do with my assets keep holding or cut lost and take profit with investing in other altcoin or bitcoin.
Take a look at the charts. Altcoins have pretty much been on a downtrend for a while already. Altcoins have always been very high risk. If you want high risk? That's what you get, high chances of losses. If you want low chances of loss, get out of crypto and go with safer assets like an S&P500 index fund.
