As I write this (Monday evening on 19 April 2021), Bitcoin has just suffered a 15% fall on the basis of speculation that major jurisdictions may undertake regulatory action (at least that's what some analysts are saying).
This to me just shows how quickly these highly speculative markets can turn, and before some one accuses me of being no-coiner or the like, I'm currently holding a small position in a crypto-backed Exchange Traded Product.
Basically, my rant here is that trading something like crypto needs to be carefully managed, but even so can still hurt. I'm trying to work out what to do with my position which is down around 8% from Friday's close and rapidly approaching my stop (at about 0.5% of capital at risk). These big swings can be hard, even if you're aware of your psychology and actively manage it and have proper risk management techniques in place.
The other thing I find interesting, despite the fall in the major crypto assets, the meme coin Doge is still climbing, go figure. Utter madness.
