Will something else overtake BTC or ETH someday?

Is there another coin out there that could possibly take over either btc or eth in market cap someday?

Personally I believe at the moment that the 3 most likely candidates at the moment would be ADA, XRP or MATIC but is there another one out there with massive potential that could one day knock off the 2 top dogs?

Could a meme coin get there? Would it be a centralised coin or a de-centralised coin? Or are BTC & ETH destined to remain 1 & 2 for a long long time.

What do you guys think? Happy investing everyone 😊
