I just inherited a decent amount of money from my family, I decided to invest in cryptocurrency money. Which altcoin should be invested long term this year. Thank you for your comments 
Don't simply seek your advice from some random people on the internet you have never met. Be ready that people will try to advise coins that they hold, because if they succeed to pump their coin, guess what they profit from that. Be careful for your money and best is to simply cross it out as you don't have it from the point you invest into crypto because it is a risky investment.
If you get some replies make sure to do your own research because it is your money anyway, not mine or others. Don't invest more than you can afford to lose and don't throw your hard earned money because this "investing" is simply pure gamble for many alts.
If we knew which coins will do the best be sure that those coins would have skyrocketed till now. Nobody knows there is to much uncertainty.
