Even considering the current price of Bitcoin, buying a hundred dollars worth of Bitcoin is not a good decision. There is no apparent benefit of investing a 100 dollar in Bitcoin.Because investment in Bitcoin requires huge capital and you have less capital. It would have been nice if you had bought a small altcoin that was worth less than a dollar instead of investing in bitcoin. you would have received  hundred of tokens for a hundred dollars that you could have profited from in the future. Because there are many good projects in the market that are currently priced at less than a dollar, And when the market goes up, there is a high chance that those small Altcoins can give you great profits. But for this it is important that you choose the best and top Altcoins.
