Can you help me see if I have an old Bitcoin account?
Do you remember writing down any kind of information, like 12 or 24 random looking words (or any other information regarding your bitcoin/crypto accounts)?
As @chytrik mentioned, there was no bitcoin or &quot;crypto&quot; (in the sense which the word is used nowadays) before 2009, and wallets that were able to store other cryptos besides bitcoin came into existence only a few years after that.
So what happened in 98/99 shouldn't be of any importance. Perhaps you are conflating something else with &quot;crypto&quot;?
In any case, if you think you might have had a bitcoin wallet, figuring out what kind of wallet/account you used would be a first step, and if you have any other kind of written down information would be very helpful as well (DO NOT SHARE THE ACTUAL CONTENT OF SUCH INFORMATION WITH ANYONE, in case you find it).
