Well that's also something we can do and I do it too, I usually invest in altcoins and take the profits and divert them to buying bitcoin. Methods like this are strategies that everyone can do.
We can focus on bitcoin, but we also don't miss altcoins. This is something that is very profitable for us, because we can maximize all the opportunities that exist.
Most of the people are doing the same thing as they buy both Bitcoin and altcoins and whenever they find their hold altcoins profitable then they invest that amount of profit into Bitcoin so in such case they will be more profitable in future.
People are afraid of altcoins investment but they don't know that the amount of profit from altcoins are also very big if they do the same things which are necessary for having a money making opportunity. We have to take benefit from each and every chance because the same profitable situations do not exist all the time so take the risk and go ahead with learned skills.
Of course, that's the right way to apply. When you make a profit on altcoins, you immediately transfer the profits you get to Bitcoin because the profits will increase even more, because Bitcoin is a long-term investment and has very little risk.
You are right, many are afraid of investing in altcoins because many altcoins are scams, but when it comes to profits, they are no less and are often even higher because the value we invest is usually greater than investing in bitcoin, whose price is already high. That's the only thing that ultimately makes the difference.
You always have to be wise and be able to find which one is more profitable because the goal is to make a profit by investing.
