In such uncertain market conditions, it becomes flaring which coins are better to hold. The absolute best would be Bitcoin, then Ethereum. These two would withstand whatever test the market has in the next 5 to 10 years so your investment is guaranteed.
Most people believe that any coin in the top 100 is safe enough, but that is not it for me. I believe utility matters a lot so I would rather stick with those on the top 20 instead.
Most of my investment though is in shitcoins, coins in the 200 to 300 range and I'm scared of selling at a loss, so I'd just rather HODL with diamond hands.
