I agree with you man, after a crash (that had nothing to do with the legitimate uses of the cryptos changing) is the best time to buy in. One thing I would point out is that markets, even the crypto markets, do not stop and turn instantly.
What I am saying is I am not buying back in yet, from my experience prices will continue to go down a good bit more and it is best not to buy in too early. You will know exactly when the crash has ended because price will stop and go sideways for a few days; when that happens I believe the best prices will be there for the taking.
Anyway man I noticed your new to posting and from what I have read you have the right mindset for investing in cryptos so I followed you to hope you will continue posting more of this solid information in the future!
