I think it is time to buy BTC and alts step by step.
We may not see this price again.
the current situation is better to buy than sell, because prices also do not allow us to sell. so if we want to sell, it's better to wait first, and now take advantage of the current situation by buying coins.
For short term investors none of the time is better as anything can happen anytime while if long term investors want to come then they have to come now to invest as much as possible as right now they can buy a lot of coins which were unable to buy in the previous year as the future will again give a high value to them.
