Not sure what to do today, maybe go into FIAT?

Market looks pretty unpredictable today, there is a lot of panic posts on forums and i'm thinking of moving my BTC into FIAT.
2 days ago BTC was going toward 680 and i've setup a buy order for 2 BTC on 663. When i woke up i saw BTC on 639 $ and i knew i did a bad job by buying it automaticly on 663. Then i did another pretty bad move by buying it on 639 $ since it sinked to 610$ later on.

Anyway that second order looks ok now when the BTC is aournd 650 so i might partialy go out to fiat with profit any maybe hodl the other 2 BTC which i bought on 663$ and take my chances on halving.

I'm afraid BTC might go back to 400-450$ which it was before the halving euphoria occured. Maybe the price can get a little bit above that because of the less supply, but im not so sure about it, i think people will run out of BTC and go find themself faster profit with altcoins. Other than that it will be a good idea to track http://blockspeed.info/ - Here you can see the number of unconfirmed transactions. If many miners shut down their business after the halving (because of 50% lower reward), number of "unconfirmed transactions" will go to the moon and the price might start crashing. Worst case scenatio would be a total doom of BTC which i don't believe in, but slight problems are pretty realistic scenario.
In that case i would feel pretty comfy in FIAT, and maybe wait for HF occuring on Ether which might trigger some opportunities for even cheaper Ether than it is as this moment.

I got out of Expanse for a micro profit, just because i was afraid to get stuck in it for a longer period of time which doesn't sound good when there is cheap Lisk on the market as well as cheap Ethereum.

When it comes to Sia, i'm still in, price is pretty low IMO, the potential is huge and i don't feel worried about waiting for a better price to sell SIA.

This is my current account standings:

It looks pretty similar as it was on my first post https://steemit.com/introduceyourself/@metropolit/hi-to-all-steemiters-follow-me-to-the-moon-or-to-the-zero

Hope at least someone had a good read and will keep following my venture :))
