To address Cryptocurrency "bubble"
IMO cryptocurrency is in a bubble but has a huge exponential chance at growth, even with halts and roadbumps cryptocurrencies entire point is to continue decentralized exchange of wealth even when the law doesn't approve, for that very reason it will always survive. Other notation is that the market cap is a mere 114BN with a total estimated wealth of 83.6 Trillion in circulation around the globe which means cryptocurrency has just barely scratched the surface. In other words HODL is a good idea but to keep HODLING is a better idea.
