Started late 2017 and made a few mistakes
- Hashflare cloud mining: lost around 500$ buying SHA256 contracts, profitability quickly decreased until they stopped mining because "not profitable anymore" and my balance never got over the minimum to cashout, even people that did claim their accounts were deleted when they tried.
- VIVO and PAC masternodes: not really a scam, but I started mining and thought masternodes were a great idea, quickly lost over 90% of my investment.
- VIVO doesn't exist anymore lost 1-2k there.
- I sold PAC (Paccoin now renamed Pac Global) at a 3k loss (80%) in february this year. Fun story is 2 weeks later it pumped so hard I would have made 10-15k instead.
- Avoided the Cryptopia scam in 2018 someone else previously mentionned. I went there to trade DOGE, but luckily I cashed out before they disappeared.
- FOMO'd in a few shitcoins this year with BTC profits, but very small amounts I was ready to loose, and I did exactly that! Mainly Elongate & SHIB.
