That is a fact. Although many investors want to compare any other coins to bitcoin, it is still impossible for a new coin or other existing coins to match the power of bitcoin. But although bitcoin is the sure thing, we can also take advantage of the other cryptocurrency out there, especially those coins that have the potential to give us profit. I get that focusing solely on bitcoin can be beneficial and is the right thing to do if you want to secure some good profits, but in order to have incomes or profits while going long-term for bitcoin, you will need those altcoins, meme coins, or even shitcoins if you know how to do so. For me, I majorly focus on bitcoin, but if there's a chance that I see other coins with a good chance of profit, I will take a risk with them, and so far, I only have a few losses when it comes to meme coins and shit coins.
