It seems to me that bitcoin is the best currency to earn on the course. The price is not very stable and fluctuates constantly in different directions. It is possible to earn and gain experience for the transition to earnings in other currencies.
Yes, you can learn how to earn money on bitcoin. But it is suitable for short-term investments, because it is very unstable and no one can tell exactly what will happen to it in a few years.
We need to learn how to gamble if we are here in the crypto world, there is no guarantee that we will earn easy money but
if we are good enough we can certainly make money from our money even with the biggest amount we can imagine.
