$DOT, $FET, and $BAND are my portfolios for the long term. I have a plan that each coin must be up to 10x the price I bought it for. I'm not very good at choosing projects, I only look at the top 200 on CoinMarketCap.
I have Dot and Ada on my portfolio hold for a long term investment as I believe this project will bring huge profit in the future. We can find other new gem to hold by searching it's project real use case. If you know the project is good and it has a trusted team you can invest. Choosing top coin in cmc is a nice choice this will be our guide on what project to invest.
