Thank you for your comments

Yes trust is an issue, but fortunately, bitcoin is 'trustless'. Am looking for one or two 40ft containerised mining rigs.....that's between 300 and 650 ASICs by my research. Along with peripherals, shipping and installation.....a ballpark figure of $3 -$4m. I would imagine any investors would be well researched before venturing close to and have done rigorous due diligence.

with mutlisig wallets all miner rewards would go directly to investors, no government can stop or censor payments.

Investor risk is whether the AICs will be switched on, or if I pack them up in a truck and drive off with them.

But more seriously the location and electricity supply is on a Multinational Multi-billion dollar industrial complex, which is easily checkable, hence I don't want to give more details here otherwise I will dox myself.

Any suggestions on the optimum ASIC's and possible genuine suppliers that I can approach.

the last research I did o this was almost three years ago.
