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
When this is good as bitcoin bull run is good for everyone. Though lots of altcoins and Exchange coins are also doing good and it's good to join the fray. I hate losses so I've set my mindset to make profit while being on guard. For now get BNB and veil and some Exchange token to build up some portfolio.
