/**
America-first strategic reserve
TG: https://t.me/AFSRETH

While many in the cryptocurrency community have been cheering on the pro-crypto executive orders Trump is expected to issue, one idea is causing more controversy: 
the idea of an America-first strategic reserve that would prioritize digital coins founded in the US, like Solana, USD Coin and Ripple.
In recent weeks, Trump has met with the founders of these coins and, sources said, is receptive to the idea.
Insiders, who spoke on the condition of anonymity, shared concerns that it could delegitimize efforts to promote Bitcoin, which is the asset they want to prioritize.
