I think people should stop asking these questions, it's becoming rampant. The answer has always been said here in this forum many times. Invest in coins you believe in, asking here will only give you more confusion.
Well, if you invest in a long time , it seems to me especially no matter what time to invest , because you serovno will wait for x4-5 ,and now you can go to all the promising altcoins , and those who like to trade it is better to wait for the drawdown
Yes if you are making plan to invest for long term then it does not matter how much you are going to invest, it is very good time to buy now because price is not very high but it has good potential to rise in future I can see good coins are getting value and being high in price for us, we should trust bitcoin today which is at good price zone price is not very high but it has promising future, it has good history and in few months price of bitcoin will be high with 4x means more than double.
