This question will resolve according to CoinMarketCap. Single trades on Kraken or you selling 1/100k BTC for $1 to your friend don't count.

Thresholds resolve whenever they are hit, with the explicit definition: "price of BTC at any point in time in April" <= threshold <= "price of BTC at any point in time in April".

The relevant timezone is UTC. All thresholds that aren't hit until May 1st, 2024, 00:00 UTC, will resolve as NO.

I've set up notifications for these (with a delay), but feel free to tag me in the comments if a threshold is hit. Mods are explicitly entitled to resolve if they choose to do so.

I might add more options later on.
