Yes, I do. For a long-term better to invest in new and small cryptocurrency because its the most profitable. New coins are cheep and you can buy many units for not a lot money – 10-100 satoshi per one coin. After a few years or several months, some project can become popular and successful so your coins will grow and you can sell them 10+ times more expensive. This is a good plan if you are not ready pay a lot money and look into the future.
The hardest it's finding true and promising projects who really wanna implement ideas and working on it. Need to be careful, check official communities, reed White Papers etc. It will reduce risks and increase the chance to find successful projects.
Personally, I work on this principle also and buy not top 100 coins all time not for profit only but for a support real good ideas and true enthusiasts.
