So bitcoin price now crash and if you have 1000$ bitcoin it may be back to 900$ tomorrow so what will do ??
Stop being so fiat centric. If you hold $1000 worth of Bitcoin, the number of the coins you hold will remain the same regardless of what direction the market moves to. On top of that, it's just a small decrease that we experience right now, and after the mad increase we have gone through in the last weeks, this shouldn't come as a surprise.
for me will exchange bitcoin to ETH and when price back to this point will made other exchange from ETH to bitcoin and get free ETH
Ethereum is in a long downward spiral, which means that this is a coin people should avoid. Governments are more and more looking to find a way to put a stop to the ridiculous number of shit ICO's, and as result of that, the number of ICO's will only go down, and thus Ethereum as well. The only thing you and others can hope for, is a pump to happen, but that would be more or less similar to gambling.
Shear us your strategy to deal with this crash ??
What crash?
