Wow! These are quite some numbers! Almost 2 million SPT is really a big stake. I really feel you, about forgetting about things. Crypto as a whole started for me with just fun money - money, I don't need and don't mind loosing (well, beyond the fact, that it is never something I want to do). So in the beginning I didn't really kept track of everything I did - and every now and then I find some projects I did interact or even invest in.
I really enjoy Hive for this reason, since it is easy and has a good overview. Althouh All those second layer tokens can be a problem to keep track of.
Cheers,
