...2013-2014 when the first big drop happened...
Do you mean the fall from $1200? That was hardly the first big drop.
The crash from $33 to $2 back in 2011 was bigger. The crash from $266 to $50 was a pretty big drop too.
Even the short-lived crash from $0.10 to $0.01 in 2010 was bigger.
There will be more bubbles and more crashes but as long as they keep getting exponentially larger, everything will be fine for long-term holders.
Bitcoin still has a long way to go before it hits the "vertical" stage of the adoption s-curve.
Well... the first notable drop, I am just trying to relate to the current situation, last time the price was over 1000$ it dropped, tremendously.
