Yes I truly believe in cryptocurrency. We all know that the basic aim of everyone for participating in any investment market is to earn profits and there is nothing wrong in that. But a person should have some realistic goals. You can invest in something blindly and then expect your money to be doubled in a week. You should research and study properly and take every decision wisely.
The subject to me is a little misleading. I don't know but it suggests a negative implication. You could have just removed the "Do" and the "?".
Anyway, as to any kind of investment, not just in crypto, there should always be a process of planning and choosing what's best. And that will not be done overnight. It has to be done over and over again. Investment is synonymous to risk-taking.
