My next big call (under $1) (Ad)

The obvious way to "bet on Trump" in crypto is the Trump memecoin. And right now it's back in the news, with a contest offering its biggest holders a seat at dinner with the President. It's also about 97% below its peak. Because a memecoin doesn't benefit from good policy. It benefits from attention. The real winners of a pro-crypto Washington are the projects with actual businesses underneath them. Ones that get more valuable as rules get clearer, institutions get comfortable, and more money flows into the market.tc pixel

Here's my #1 pick for the Trump crypto era.
