I was present during that chaos on 2013, but i just introduced my self on bitcoin (i started buying) lately on 2014.
Of course almost every fundamental is now different but human psychology never changes.
The super bearish trend is not going to happen again, just because a lot of millionaires, billionaires, institutions, they all are introduced in bitcoin.
In 2013 the blockchain was just full of normal people that were spending their coins just in videogames or any other bullshit
Now it is different, bitcoin is considered as money, no one is going to lose the opportunity to make more money from that money.
it is not going to happen it again, just becaus of that. The whole market is prepared to face that situation, and if it drops a twenty or thirty percent, there is nothing to be worried about, because the price was 40 percent lower a few weeks ago (one or so)
