Investing bitcoin is really risky!
You should hold ot for some times, it's the best thing you can do!
Buy&hold bitcoins is risky, but it's possible to use strategies that dramatically reduce volatility and you will still have double digit returns
Strategy #1. Multi-crypto currency portfolio. It will reduce volatility many times in comparison to 1 asset portfolio
Strategy #2. Hedging with deriviatives
I manage a portfolio of crypto assets that has current yield about 30-50% APR and very little volatility in comparison to bitcoin buy&hold
