I got 0.8 ETH from Bounty in 2019 and I kept it on exchange for 2 years, surprising thing happened when ETH price in early 2021 was above $3k and I am still holding ETH for long term, from here I can learn to hold Altcoins and choose Hodl to get a big profit, no one knows the price of a particular stock or coin will go up or down, but all options will pay off and don't panic when investing because it can cost you money.
