From time to time, I get paid in BTC for my freelancing services. Sometimes, I don't exchange it to real cash and let BTC sit in the wallet. But lately there has been A LOT of fluctuation in BTC price so if I have, let's say, $2000 today, tomorrow I might have half of it. I don't like that kind of a situation. So is there any way to make sure that your BTC gets fixed? Like, somehow fix the BTC price in your wallet. So no matter if actual BTC price rises or falls, you still have the same value that you have today. I think I might be interested in keeping some of my savings in BTC (away from banks) if I can somehow find a way to fix the value that I have today.

Is there a way? Any suggestions?
