Sorry for late reply...
I don't actively "trade" crypto either. I played around with trading Forex a few years ago, but I just couldn't get into it.
I do "daytrade" part-time (3 days a week). Mainly Index Futures (SP500). I may play around trading some crypto eventually, just to do it. But it's not high on my priorities right now.
My main cryptocurrencies I have at this point are BTC and ETH. I started with Bitcoin, May 2017, with $10K in BTC and by end of December 2017, BTC's value had run up close to $20K.
BUT.. I sold half my BTC early December 2017 well before it got to that $19K+ point. I "bailed" when BTC was about $14,800. NICE profit, though, and STILL had the other half of my BTC holdings to HODL!
I still wasn't totally onboard the crypto thing at that time and didn't "buy in" for more yet. But a year later, 2018, when BTC ended up nose-diving all the way down to $3400 in December 2018, I decided to get back in at that $3400 point and add the same quantity of BTC I had sold the previous December (2017). I am STILL HODLing them!
Did pretty much the same thing with Ethereum. Bought $10K of ETH in November, 2020, then sold half of them in October 2021 @ $4150 for a NICE profit. Have been HODLing the remainder ever since.
So, for me anyway, right now... IF BTC & ETH were to go all the way down to $0.00 (ZERO), I would actually lose NOTHING (ZERO). It will STILL have been quite profitable for me! But I doubt it will get that low any time soon.
LOOK... It's NOT for most people, but if you can handle a bit of risk and can think a bit "long term" , this has some pretty good "potential". Just don't go crazy and go in for more than you can afford to lose. It is STILL "speculation", after all...
