in fact the best way to make money is certainly to "altcoins" but not all of them.I guess the bitcoin has now reached the required repletion. no matter how much money you are, it is very difficult to make your money with a bitcoin investment.but on the other hand if you can find a really solid project you can double your money in a very short time. we have seen more of this kind of projects that have multiplied themselves but we do not see them so often because of the situation of the market. it is already a waiting period. altcoins should definitely be taken when the market is fully stabilized. but not now i think.
