Bitcoin will be the best coin. You don't have to buy other coins because the other coin will have risk, especially if bitcoin price is down. But if you buy bitcoin, especially if you buy at a lower price, you will see how big your profit later when the price starts to increase. We don't know which coin that grows at the end of this year, so why do we risk our money with something that is still unknown? Although bitcoin has the unknown about the price, bitcoin as the leader in the crypto will surge to the high price, and I am sure that you will make a big profit later.
