Great, so I can put in £200 at the start of the day before work, then when it gets to lunch and the bitcoin market is currently crashing, I can withdraw my full savings now valued at £2 and buy half a sandwich, bargain!
It has gone up 100x in a few years, though.
With this, you can escape large parts of the banking system and control more of your own money in a more granular way if you choose to.
But really, if you are at all worried about losing all your money in crypto, then you should only invest a little, and.. sell 50% once you 2x.. or sell 20% once you 5x... depending on how worried/patient you are.
or any combination you're comfortable with so that losing "1x" will not put you worse than you started.
Can't afford a whole bitcoin? Buy a half, or a quarter, or an eigth and apply the same strategy..
Yeah, of course it could go to zero before you gain, but really, it's not looking like it. There has not been a better investment opportunity in our lifetime as what we're seeing now.
I think it's crazy that so many people who know about it are still hesitant to put even a modest amount in for fun.
