pockets – Attempting to recuperate outdated BTC from a pre-2013 centralized change — I’ve my electronic mail, a 5-digit code and an MD5-like hash, however do not bear in mind the platfor

Again round 2012–2013, I bought some Bitcoin on what I imagine was a centralized change. I by no means touched them since, and I am now attempting to recuperate entry.

This is what I nonetheless have:

• My outdated electronic mail handle used to register
• A 5-digit code (probably a PIN or account identifier)
• A 32-character string that appears like an MD5 hash or comparable cryptographic fingerprint — it is too brief to be a non-public key, and comprises non-hex characters, which suggests it may be a platform-specific token or session ID somewhat than a regular hash

I do NOT have:

• The identify of the platform (I genuinely cannot bear in mind)
• A seed phrase or non-public key
• A pockets.dat file (so far as I do know)

My questions:

1. Might this MD5-like string assist determine which platform I used?
2. Is there a solution to hint again which change was related to my outdated electronic mail, based mostly on the kind of identifiers they used on the time?
3. What have been the commonest centralized exchanges earlier than 2013 that I ought to strive first (Mt. Gox, Blockchain.data, Coinbase, BTC-e…)?

Any steering can be significantly appreciated. Thanks!
