Absolutely yes, dropping of prices is the right time to invest a huge amount because in this way you can earn more profit when the market goes back to normal.
If you have big investment I suggest to invest in different coins like bitcoin, Ethereum, Ripple etc. it will be better than putting all your money in one coin. The prices of almost every coin are low and this is the best time to buy more and more crypto. Those who didnt sell their coins for low price will be happy now due to increase in the price. They will earn good profit.
