"Not that profitable" is way much better than consistently depreciating. That's Bitcoin versus fiat.
Here comes Bitcoin. We're safer with this one. It is volatile, yes. Its price could crash anytime, yes, but it is still generally going up. So even if you are not after the profit, you may still safely park your savings in Bitcoin. Gaining a little is better than losing. Gaining sometimes is better than losing all the time.
I respect that, but shouldn't this be an opportunity for small amounts to become bigger. If you want to safely park then you might as well just put that money in blue chip stocks because there, there are dividends as long as you are an investor.
