this is the best time to invest, because some of the coins I see dikripto market are very cheap, but you have to be careful and see market movements, so you don't lose a lot of money.
What is the difference between buy and invest ? In my opinion both these are the same thing. We can do buy or invest the right now because bitcoin prices is hitting the bottom and from now onward we may have positive trend. So, there will be more chances to have multiplying our investment.
