I think this aint no bubble at all my friend.
It is merely a much needed market correction.
Overal we are still 100's of percents up from lets' say the beginning of this year.
If you look at the total max. marketcap of the whole crypto-sphere which was ~112 Billion at the last height point.
This a fraction of what the total is being traded in stocks,bonds,derivatives etc.
It is bound for at least a 10x increase over the next 5-10 years being carefully optimistic.
This crypto industry is still very young and immature,current correction has to do with ICO's converting capital to fiat to do real world business,causing so called dumb money to fud out,also especially with the 1st Of August deadline .
They will be back later when smart money have strengthened positions, prices soar again and institutions on the sidelines now are reasurred the market is maturing, start to play the game.
Then serious bubbles will start to develop if there is no regulation in place.For now enjoy discounted prices,millionaires will be made again soon.
