Using several sites i was able to determine to which sites/exchanges some of these adresses were belonging.
Out of the 26 adresses i've found 6. This leaves 20 more adresses which are unidentifiable.
Out of the other 20 adresses that are unidentifiable, it seems that they're almost all also belonging to some kind of exchange, as they're usually connected to hundreds of other adresses. https://imgur.com/a/dXcVJoH

Only 4 adresses are from a wallet consisting of <15 known adresses. You might want to take a look at those too if you think you might've used a wallet such as electrum.
