Hey, looking for advice on building out a small mining operation. I have access to cheap hydroelectric power in South America and a $50k USD budget for hardware and infrastructure.

Main question: which ASICs are the best efficiency/price ratio right now for someone starting fresh? I'm looking at J/TH as the key metric given my low electricity cost (around 8 cents per kWh), but I also want to avoid overpaying for the newest gen if mid-gen units give better ROI at current difficulty and BTC price.

A few specifics:
- Climate is warm year-round, so I can't repurpose heat for anything useful – cooling and ventilation will need to be budgeted for
- Importing hardware to South America adds logistics complexity – has anyone dealt with customs/duties for ASICs in this region?
- At $50k scale, does it make more sense to go all-in on a few high-end units (S21 Pro, Whatsminer M60S) or spread across more mid-range machines for redundancy?

Also open to hearing from anyone who's done the "mine vs. buy spot" math recently at this power rate. Appreciate any input.

Hola, estoy buscando una forma de cambiar criptomonedas (USDT) por USD en efectivo o mediante transferencia bancaria local. ¿Conoces algún exchange P2P en Ciudad del Este o alguna solución que pueda usar? Soy inmigrante y estoy intentando traer dinero al país, pero el banco bloqueó la transferencia internacional en Paraguay y me pidió muchos documentos, algunos de ellos apostillados, a pesar de que no se pueden apostillar. Llevan semanas reteniendo la transferencia y necesito el dinero aquí.
