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.
Sorry to be a little different. I don't believe in Bitcoin as a currency. I don't believe proof of work algorithm is the future. The world is moving towards proof of stake or a decentralized proof of stake or DAC graphs. Proof of work has its own disadvantages and in future with the quantum computer and it's computing power you can technically hack any proof of work system with a 51% stake. Therefore I'm doubtful
