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.
New projects are all high risk investments you never know how they will develop, perform or end.
Even the best looking projects can fail, the only good thing is that as they possess high risk the potential profit can also be huge and it depends on the level of success of the project. I have seen people making life changing income from new projects.
