If you could go back in time and alter one single crypto transaction you made what would that be?

Looking for more realistic answers here not the I should have bought $10,000 in Bitcoin in 2011 instead of $1

When I first started getting into crypto I bought 27k doge coins at like .045 and I sold at .06 because I was convinced it would never reach a penny. I know it’s not a life changing event and who knows how long I would have held on but it’s still gets me.
