we are already in 2020, of course everything is different, 2017,2018, and 2019 has passed, I'm sure the coins or tokens that you hold will now increase and slowly improve, look at the price of Bitcoin slowly improving, even though the ATH is at $ 19000, but the price of Bitcoin could touching $ 12,000, not bad, I'm sure altcoin will also go up 2-3x
If the project is good, one day the price will touch ATH again even though the price is still slow, I also still hold a few tokens and hope that there will be a bullrun/altcoin season this year or next year, although it seems a bit difficult because more coins/tokens are release on the market.
You just need to be sure it will grow even though you can't be sure in the future, you can see for yourself the shocking price of bitcoin that no one realized at the end of the year until now.
