According to Bitcoinist, the data shows that if you buy bitcoin worth $100 in mid-2010, you will get $1.3 million today. Of course, the premise is that you can hold it. In contrast, all other cryptocurrencies were traded on the first time, and the return on investment was not as good as BTC. Since its debut at the exchange in 2015, ETH has been the best performing competitor. A $100 investment in 15 years will now bring you a return of $68,000.
