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.
I still believe, because there are still many people who invest and seek profits and profits in terms of buying and selling in bitcoin and crypto.
