Some say altcoins pump once, then it´s over forever. But that´s not always true. If the coin has real technology and usage behind it we could see it go to the moon in the future. Which altcoins have the best potential to stick around and create gains in the future?
At least you learned from what did before in selling your ETH, but it is still not too late to accumulate your earnings in ethereum, then hold in the long term. However, DOT is also has a high potentials to get higher in the future here in cryptocurrency. In fact, I am holding dot as well even a few of them only.
