Look at mempool, choose a random block and filter for OP_RETURN:

90% of transactions are OP_RETURN and if you click at a random transaction probably is a transaction from a address to the same address like this: https://mempool.space/tx/3bdc9fd75a4afcf6987a751f16eca6e28a92a59cf5673b428136e3171199c355

Bitcoin is no more used as peer to peer cash system! Is used only for memecoins, casino, and layer-2.

Thanks for David Bailey and Segwit developers.
