RE: Bubbles and Cryptos
There is a common acronym thrown around now, well, two, relating to the benefits of early adoption in finance - FOMO and FMA...
I think that the utility, and especially when it is outside of the parameters of those kinds of services offered by banks, like Steem Power, for example, an automatic savings/disbursement system, will distinguish those that really stand out in the growth rate race. Privacy and fast transactions are the two things that will decide where all the money eventually pools up, as will the right rate (or no more than a threshold) of inflation of supply.
A lot of cryptos are just riding on fancy marketing and not really actually practical schemes. There will be a shakeout, and how astute you are at discerning what is useful and what is just waffle will decide how much you win or lose.
The shakeout will indeed happen. But it may take a few years and those years attract a lot of bright minds and capital to the game. Unfortunately, this is necessary to advance.
It is by no means possible already to determine who will survive.
Because of the popularity. The value of cryptos are going up. Though some may not be as good as btc or eth
