I haven't logged in or used my accounts for so long its nothing more than the computers that hosted my accounts are fried and I didn't keep any backups as I was 18years old/19 years old when I bought these accounts..
I don't understand.You bought theses accounts,or you bought the Bitcoins in the accounts?
From where have you bought those Bitcoins and what was the Bitcoin price when you bought them?
If anyone from blockchain or bitcoin could get in touch with me
Bitcoin isn't a company so nobody can "get in touch" with you.Blockchain.com has customer support,but you will have to provide your private keys,which you don't have,so they can't help you.
Anyway,assuming you are the real owner of those BTC,I guess that this is one of the many horror stories of early adopters,who lost their Bitcoins due to damaged computers,forgotten passwords and keys and BTC sent to the wrong address.Yeah,that sucks,but nobody can help you.
You could hire someone to crack the passwords/keys,but this will take 1 million years.
