last 2 years i would say yes. but for now i dont think so. bitcoin been increasing so high but its stop and drop from 20k$ to 15$ and it hit the market so much. i dont think investing in bitcoin would bring any money anymore. better invest on altcoin or the new ico.
bitcoin is the most profitable investment of nowadays and it is wise to invest into bitcoin because its profit rate is impressive and its eases are also magnificent and on top of it bitcoin is accepted all over the world and it gives more than a 1000$ profit in one week time and thats a great figure so invest onto this coin you will get what you want or more than you want this coin has potential to deliver 100% profit.
