Everyone is holding, that's true. But the question is what coin are you holding. Some alter coin will never turn green. Because it's already dumped. But I still believe holding is a good idea. Hold a little more, for a little increase. Because the raising and falling is the joy of crypto trading.
The correctness of any action is understandable only in comparison with another action. If we compare the holding of crypto assets with the investment in a bank deposit, then obviously this is the right strategy. A bank deposit can not protect an investor even from inflation.
If you have stored your amount in the banks and you will be only getting a little interest from your amounts. The bank has the more protection to the users because it has supported by the regulators and i guess you need to learn more about this dude.
