suggestion for being in Venezuela: buy physical dollars and sell them in Colombia and a friend who has bank accounts and a Binance account to buy USDT from you and you sell it in Venezuela

Good day to everyone, I am seeing many Venezuelans saying that it is an abuse that in Binance the purchase of USDT is sky-high, if the BCV has it at 140bs, here no one buys dollars at 140, no one, the sale of dollars in Venezuela fluctuates around 180, and from what I have read Binance has nothing to do with the Venezuelan economy. For me, what is happening right now is that many are buying and holding, and no one wants to sell, and there will come a moment, and I estimate for September, November, and December, when everyone will sell.
