A letter from Shannon Stansberry (Ad)

Porter Stansberry nearly canceled the entire project. When he first saw the claimed returns - only one down year in nearly two decades and total gains of almost 2,000% - his immediate reaction was disbelief. It took a trusted friend's personal vouching for Emmet Savage and a face-to-face trip to Ireland to change his mind. The full documentary, Investigating Project Prophet, is now live.tc pixel

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.
