The dot.com bubble took about 4 years to burst. But I wouldn’t give this one as long. Probably about a year into it proper now. This is almost a mirror image of the internet bubble. People confused the internet (good idea) with makey-uppy internet businesses (bad idea). Now they are confusing blockchain (good idea) with makey-uppy blockchain businesses (bad idea).
Have a look at the business plans for these “ICO’s”.
Aiming to create a multibillion dollar blockchain lottery.
_A blockchain that interacts with the real world. _
A blockchain based genomic (DNA) ecosystem.
A decentralized platform for connecting doctors with patients
A blockchain based invoice exchange
Probably take at least a year before all these ICO’s burn through the cash and be found out for the frauds that they are, some of them will probably raise more money at an inflated valuation and keep plugging on, but then suddenly a few will go sour and the whole thing will collapse like the house of cards that it is.
