So true.
I tried splinterlands before. Twice. Spent $100's of dollars, and with regular playing it might become thousands of dollars.

But didn't think it would blow up like that, so sold all the cards cheap.

I am trying a few battles daily now, with rented cards, and buying a few cheap ones.

If I am still interested/involved in the game after a few weeks, I might buy some more cards for the long term.

There is no turning back clock, but we can look back and make better decisions in the future. The benefit of missing the opportunities maybe🙂
