Use your backup 

First support is 470$ (previous bull flag + Fibonacci retracement), next its 350$

All of us who have fiat reserve are happy about that crash
Its a normal cycle, when the price will be down enough to match demand, we will grow back again

although exchanges are not a part of bitcoin itself, I see them as a part of his ecosystem, and many people have no choice but to use them. therefore I think it's a problem to be addressed and not to be overlooked only because "they are third-party services"

bitcoin have a public and trackable blockchain: it doesn't seem to be focused on anonymity. but there is many problems that exchanges bring, I think most of you are aware: extremely slow support, downtimes, stolen funds... all this attack the core ideology of blockchain

the solutions are DEX (Decentralized EXchanges), the most advanced right now is bitshares
atomic swap can also be a part of the solution, although slow processing would restrict ability of traders, and would be mainly useful to simply swap one coin to another (if both support it)

there is a thing between day trader and holder.
here is how I see it:

• scalper: works with 1m, 5m charts, do a lot of trades per day
• day trader: works with 15m to 4h charts, never hold his position more than a day
• swing trader: can hold his position for several weeks, months
• position trader: holders/investors. can hold a position for a year and more
