I would recommend you checking the Top 100 or even Top 10; especially if you want to HODL long term. Everything beyond the Top 100 increases your risk of picking a dead end project or scam, even though you could get the most growth out of a smaller project that might be "under the radar" right now. But don't get confused if a shitcoin had a good run in the past - because this is common during hype phases or might have been a pump and dump.

Since you probably have no experience in what to look in a coin chose one of the proven coins. I think picking one of these give you the least risk in the long term BTC, ETH, IOTA, Litecoin, Monero etc.
Personally I do not like Ripple and Tether but thats up to you. Additional:  some of the Top 10-20 coins are trying to solve quite similar problems in different ways so think about that when you pick them.

For example you can pick all "ETH clones" in the hope at least one of them survives in the long term -or- you can spread your money on completely different projects (Currency, Privatecoin, Cryptoasset, Securitytoken and so on).
