holding an altcoin is the best choice, but if you look closely at the annual altcoin it can make speculation how we can choose a good altcoin and potentially get an annual profit.
We can earn annually if the project keeps on finding ways to earn, if there we are updated and know that the project progress then we can assume profit.
There's a lot of altcoin can be hold and gain huge profits but not all of them, if you look at the platforms or the potential of it will be possible to take the right timing.
