Good day, mates.
My strategy is to buy coins when the price drops sharply.
Sometimes I fail, because the price drops more than I expected.
But, to prevent this worse situation, I put 30% of my budget at the time of initial investment.
If the price getting down again, I put 30% more.
With this strategy, I am getting some money so far.
In conclusion, I recommend you guys to buy coins when they drops rapidly.
After sharp drop, there should be sharp rising.

it is a good opportunity for everyone in in the right time we have the the opportunity and we need the opportunity once if suddenly happened we need to use the chance otherwise it will not came again so when the price Rises everytime suddenly it drops it is the right opportunity for everyone to invest.
