A nice crash but I guess we will made it in a few hours or days until the market stabilizes again and goes back up. Hard times for sure, be need to stay calm and think rational: See the blockchain and not just the short term money.
The technology behind it is just revolutionary and will change the world for sure. There will be many up's and downs but I am sure the market will rise high in the next months and years.
I simply recommend that all shaky hands do nothing while we are going through the Elliot wave on the supposedly sinking ship. Wait until the market has stabilised and then buy back if necessary. Don't sell your "losses"! You'll be happy when the prices start to rise again.
Personally, I'll do some shopping at the lowest point. I will orientate myself on good, renowned projects with a bright future as for example:
STEEM, ETH, BTC, PAY, NEO, IOTA, DASH, PRE, SEND, OMG, SUB, just to name a few of my coins.
Cryptocurrency will have a bright future and in my opinion there is no chance that cryptocurrency as a whole will fail. There are just way too much possibilities out there to use it. I mean look at STEEM.
I wish you all good luck out there
