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
My choice is almost the same. It is evident that Bitcoin should be the #1 crypto that we hold. I plan to get up to 70% of BTC in my portfolio. The rest 30% are spread between OmiseGO, Ethereum, Litecoin, and Monero.
