yes, there are many just looking at the short term profit potential with pump and dumps - and its kinda sad, as damages the integrity of the whole space as scamsters hop on to take advantage. I suppose that is one downside of a lack of regulation. nonetheless, people must accept responsibility for their own choices, do their own homework, and conduct their business like big boys & girls. it's inevitable some won't have all honorable intentions - yet, there is a whole other segment who are approaching the same space very professionally...

the banks are already implementing blockchain, realizing if they don't, they're done. will be interesting to watch the race - whether they can keep up, or new decentralized platforms really do away with the need for banks altogether over time. granted, that'd take a fair amount of time given so much of society's infrastructure is intertwined with the banking system as it exists. though, the new systems could accelerate quite fast.

alot going on in this space, alot to keep up with. though again, I recommend reading Blockchain Revolution, as it's probably the single best condensed source of a holistic vision for the direction this is all going... :-)
