Risk is always there, and there is nothing wrong with making mistakes or spending your funds wrong, but it's important to improve upon them.
While taking such risk, it's wise to know what you are up against and also be confident to accept the losses that comes afterwards. Some persons are only pressing forward in taking those risk because they are expecting a huge profit in return, they don't tend to think that the market is dynamic and can still fail them if they don't take their time to make an accurate analysis for the market direction. One need to learn from their mistakes and improve themselve.
It depends on the risk we are taking as well. I mean if you are taking some useless risk then its not ok to take those risks just to learn later on, because you should already know about it and not make that kind of mistakes to begin with. I mean think about it, there are tokens which are memecoins and not even in the top 3000 list at CMC, and there are people funding those, do you really need to know anything before not investing into those?
You should know that there isn't really anything you could make money from those and that is why you should avoid them, there isn't anything you can learn from that, you should already know this. Of course you could make mistakes, there are levels of mistakes that is acceptable and that could make sense but that's only acceptable if you take a risk that makes sense to people as well, otherwise if you are investing into something shitty then do not consider that as a risk that you should be taking at all.
It boils down to the view of it by you yourself and others in such case, really

For some it's dumb, for some - it would be genius. Then again, on the memecoins, I agree with you - you can't make mistakes with them twice when you know what they are about.
Learning do comes from real experience and this is something which is really that unavoidable or something a natural thing for someone to experience it out on which we know that mistakes would really be something that makes us even more better on next time we do encounter things since we are already wary into the conditions or situations that we are really that into. It would really be that impossible that you cant
be able to see up on what are the things that you would really be gonna need to do to lessen up the risks on losing even more. As speaking for taking up some revenge on the market then this is primarily a behavior of a gambler on which we know that applying gambling approach towards trading will really be no good and something that could put up you in trouble rather than on benefitting you out.
This is why on the time that you do hover yourself into crypto trading field then always be prepared into those unexpected u-turn of events specially on trend and sudden sentiments or news that could happen on point
on which this could really that greatly affect the price without even making yourself getting prepared on what are the positions you would really be making. Its important that you should
really be knowing on what you should gonna do on which at least have the idea on what would be the best approach towards it.
