I think everyone with at least half a brain knows we are in a bubble. What's the reason of latest Bitcoin increase? 100s of thousands unconfirmed transactions? How about all these crowdsales and ICOs based on Ethereum? All these "exciting" projects? Why DGB is close to 900 satoshi? DOGE? My personal opinion is that the price of a coin (or whatever) should be justified with usage and I don't think that usage of digital currencies has increased THIS much. Don't get me wrong - I'm also excited with the latest BTC increase and everything, but I'm always thinking about the future and now I think it looks scary...
We are in a bubble, but question is where. Are we at top? Or are we at start? I think we are not at top. All crypto marketcap only doubled in last month. in November 2103 it went up x5 in one month. So this is a big question. How long till bubble will burst. If it will take months then we are still to see huge price grows.
But one thing is sure. 2019 will be 2014 again. Depressing year when price of all cryto will decrease and everyone will cry crypto scammed them.
