Re: Don't jump into bitcoin investment without understanding it.
before investing in bitcoin it is very essential to take your time to understand the risks involved,
Take your time, but don't take too much time. 
because you are to hold bitcoin for a long period of time 4 to 10 years or more.
There is no rule as to how long you should ideally hold your bitcoin, I think. Don't sell quickly before your target, which means you should have a target. Some people's targets are farther than those of others and will take longer.
