Coins that are suitable for the long term in my opinion are in the top 30 or 50 coinmarketcaps. With a marketcap value that is still low and also actively traded on exchangers, I think coins and tokens that are in the top 30 or 50 coin marketcap can be a good investment choice for the long term
I wouldn't be so sure about some of those 50/30 top cmc coins.
I mean you will not lose more than 50% value of your funds, but most of them do not seem to be rising.
The easiest example is xrp - it is falling constantly for 3 years already. After 2017 crypto boom people were cashing out their xrp non stop when they saw any slight chance of growth.
And thats only one xrp, Im pretty sure there are plenty of other potentially dead coins
