Altcoins are really scary, if you can do some research you will see many good altcoins that had very good start and value in 2018 and are still alive today but we never heard anything good from them anymore for some reasons, they are now like ghosts, honestly altcoin investment is more scary, this is why its better to always take profit, most especially from new altcoins, Profit is Profit, either big or small.
if you fear to invest in altcoins, just don't do it buddy, because the basic rules of investments is invest only what you can afford to lose,
if you buy some good altcoins in the time when you write this thread, i think you already get some profit now,,
