Looking for feedback on an idea for a Pvp crypto prediction game!

Hey everyone! So, I’m looking for feedback on an idea for a Web3 prediction game, I’ve been working on.

So currently, I have thought of 2 game modes.

First is Quick Prediction Pools, the Idea goes like this:

You join a short round (15-30 seconds) and predict if a token’s price will go up or down.

Everyone places a small bet, and those who get it right split the pool (minus a small platform fee).

Do you think this fast-paced gameplay will work? Or do you think something crucial needs to be changed?

Second one is PVP Duels with action cards, it goes like this:

1v1 matches where each player picks a direction (up/down) and plays one card (attack, defense, or utility).

If your prediction is correct, the card activates and affects your opponent.

Each player has HP. First to 0 loses the duel.

Some card examples:

Card 1(Fire): deals damage if you guessed correctly

Card 2(Reflect): returns some of the damage

Card 3 (Freeze): delays the other player

Card 4 (Blind): hides your move

For the MVP, cards won’t be NFTs yet, but might become tokenized later on.

Do you think, from description, this game is both fun and has strategy? Or, maybe, something is unnecessary or confusing here?

If you have any other opinions, please let me know.

Thsnks in advance!
