As for when the Altcoins season will come, I think it depends on when Bitcoin will stabilize. Now is the time for Bitcoin to perform. As Bitcoin gets higher and higher, when it stabilizes, I think the Altcoins season will come. According to 2017 Years of experience, I think there will be a good performance in 2021.
Altcoins don't seem to be able to disappear from the shock that bitcoin can suddenly change both up and down in a matter of days. obviously altcoins are not going to follow that direction.
because usually altcoins only follow the movement of bitcoin which is indeed in a stable state and does not change quickly.
for the next year it will still be difficult for altcoins if you don't get away from the very strong dependence on bitcoin, you don't want to try to be able to mobilize yourself with the abilities you have. because bitcoin will still be in its best performance until next year, so altcoins must be able to change immediately and it is visible that they can start to get used to it even though it may be a little late. but there is progress at the attempt not to be able to escape from dependence on bitcoin continuously.
