Bagging coins for the purpose of stocking it in your portfolio is one of the best method a trader can earn profits. HODL more over like Hold for Dear Life is one of the major thing that have keep me going in the space. I have bagged Many coins over the years but some pump while other drop massively in price. The only key to excel in this space is to exercise patience and and keep holding some future coins whose roadmaps are promising. Perhaps market dumps and pumps sometimes, it's all a matter of time to know when all these actions will happen.
I think everybody needs to determine there own strategy. Right now I also still holding all my coins, but when we see another bullrun, I will probably sell 50% of my coins and just buy more established coins as ETH, BTC, DOT, BNB,... Nowadays I am invested in too many projects (such as FIL, GRAPH, XTZ,...) and I am not really sure if all these coins have a bright future.
