I see this kind of dump so many time since I entered crytoworld and now sometimes I hope for the price to go down like this because I can buy more coin. This is actually a great opportunity to have more bitcoin because the future of this coin is great and I can say you have nothig to worry about, in just short term you can have the profit.
You spotted it so right. Just to explain your point, remember Eth went down to 370 USD on Apr 1, 2018 and jumped back to 800 on May 6, 2018.
All this swing happened in just a short span of one month. Those who have courage to buy during DIPS are the ultimate winner.
