From what little I gathered concerning China and Korea and such I feel that regulations could potentially be the most damaging to crypto if it were to happen. Hopefully it will not especially when it is all beginning to become more and more widely accepted. heck I learned a few days go that even Starbucks of all places may soon implement crypto currency. Crypto Brokers falling over could also be a very large blow and if both that and regulation were to happen at same time..Yikes!

Hmm indeed panic selling is not a good idea I think you are on the right track there holding them all. So the best course of action is to hold them till just the right time when the value is not super low and then start using them.
