I think the best coin to HODL is still bitcoin ,65% of my money are in bitcoin and the rest on altcoins like ETH and LTC ,gone are the days when you will see 2000% of altcoins ,bullrun has been around for months now and altcoins aren't favouring that much,they will be profitable but not just like 2017 pump
Bitcoin is a valuable cryptocurrency and every peoples in crypto are using it.
But sometimes top altcoin like BNB, have more profit than bitcoin because the demands is huge.
We must find that kind of coin and keep holding it, so we can gain max profit from it later.
