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 also believe in cryptocurrencies, but it is not always possible to invest wisely. Sometimes people give in to emotions and act on them. Totally agree that before you buy coins it is necessary to study and analyze it.
