Looking at the investments I made in altcoins this time last year they are now at less than half the price.
I know of a number of coins that did their TGE last year and are now at different positions above their ICO price, some X2, some way higher.
And there are also those which have failed to rise, and fizzled out once listed. Admittedly, some projects take a while to reach it's potential.
Finding a good investment is the key, and never make excuses when you pick a bad project, look for where you went wrong and look for a solution.
