I think it’s right. Bigger profits comes from investing only on Bitcoin than investing on several altcoins at a time, and that’s based on my own experience. The price of Bitcoin fluctuates heavily than every other cryptocurrencies in the market and let’s assume that you invested $60,000 right now, you will make bigger profit from it than when you invested the $60,000 in altcoins. But I’m not saying that this happens all the time, but it is most likely to happen.
