There are some valid points made in this post. I am fortunate that a good friend is obsessed with Crypto and has been for a few years now. Invest without doing your homework and you might as well throw your money down the drain, if you fancy a dabble, treat it like its money you can afford to lose then enjoy the wins and forget the losses. Last year I made ~£10k from Crypto for around £1,200 costs whilst still investing in more. Like I say, I am lucky, my friend is a walking encyclopedia on the subject and I just hang onto his coat tails. He helps write and program a number of crypto exchanges also.
I currently mine Chia (holding ~80Tb of plots) and have rigs mining Ethereum - the ethereum is usually sold to buy other coins or tokens.
I am currently mostly invested in Just Money, Safemoney and Zenith. The hunch is that Just Money (Token) and Zenith will come good.
Its likely that I have lost ~£2k because of mining and investing in Grimm (as Raj mentions, some projects just die, this one has, not sure of the circumstances but its more suspect as the months and years roll on!). As also mentioned, some coins and exchanges are flawed or going to run out of capacity sooner rather than later. Bitcoin being one, there will soon come a point (2028 ish) that it implodes, already the speed of its own exchange systems is drastically slow compared to the newer systems.
As easy way to play the game is to get a crypto.com card and just play the staple coins - e..g fun to have a flutter. That said, I much prefer the tokens they are more fluid and adaptable using the bedrock of the more stable coins.
