Looking at the investments I made in altcoins this time last year they are now at less than half the price.
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.
I agree with you there however the vast majority of alts have lost more than a years worth of value.
I dumped a lot of non performers last year but kept the following because they seemed to have a lot of potential.
QTUM - disappointed to say the least with current price
Zcoin - hasn't lost too much value
NAV - lost a lot of value but i really like it
Altcoin is currently undergoing development so increased. with this increase will be very capable to generate the actual price and advantageous for many parties. making the real price.
