No and no

Already invested some of my money. You have to carefully read about the coins you wanna invest in. There are lots of scam coins out there. And for a considerable gain be on the look out for ICO/IDOs backed by well-known companies. For example a take the coin "MyNeighborAlice". Each Alice token was sold for 0.125 US dollars in its ICO. Almost a week later when it was listed in Binance Exchange it started with $16 for each Alice token. More than 100X profit in a very short amount of time.

i think if i did then i would've invested in it already

Tbh I bought some dogecoin because I thought it was kinda funny, it's gone up quite a bit thanks to the media coverage and elon musk

I did once but my dumb ass spooked out. I bought £50 of Litecoin one day as a hitch... I took it out some time later and moved it to Bitcoin. That evening the value of Litecoin quadrupled.

No store in my city accepts payments with cryptocurrencies, so I wouldn't

I've been a bit tempted to put in a £20 punt into Doge Coin... but I think it might be worth waiting for the hype to go down on cryptocurrencies for a while. I trust Bitcoin but its massively overvalued right now. Its certainly a way to make money quick - but it feels a lot more like gambling than investing.

I put money into them in 2017 and could multiply my investment by 8 so far. I hope i get out of this cryptomeme before its too late

No and no. The latter due to the fact that I have a basic understanding of how that works and the former due to extreme volatility of value. Might though be a good high risk investment chance for those who can afford that risk.

not really, they're too volatile and I think the price can only go up so long, because it's kind of like a pyramid scheme. i don't really know, though, i haven't studied the issue.

Feel like it's too late in the game for any meaningful gains, but as a currency? I'd trust, yes.
