Cryptos and NFTs became so popular that I also invested some funds in crypto which I was unlucky to have done that on fake Ads platform where I lost 45k . The time came to withdraw and I was asked to deposit 20% of the money before I could withdraw< this immediately made me realized It was a scam. 
I happened to make some research on how to recover lost funds and all fingers pointed to using a hacker for hire service. I ended up finding on deep web Sniffingnose ATrepairman DOTcom. I was asked to provide the Trans ID and the hash to certify that I truly made the transaction. it took roughly 48 hours for the recovery process to be completed. The site was later shut down with DDos which I absolutely paid for that to happen. This is exactly when I knew what DDos was as the hckers had to explain exactly what was done.
For as long as I know, I am never getting into crypto anymore as this was an eye opener.
