I would never in a million years try to convince you about anything amounting to investment advice.  

How you choose to invest, speculate, and/or gamble is entirely your own decision and responsibility.  DYODD.

If somebody promises you 'a sure thing' or 'a can't-lose proposition' or a 'guaranteed moneymaker' grab your wallet and run because it's a scam!

Bitcoin mining is extremely risky because it depends on crazy volatile factors like global hashrate/difficulty, fiat/BTC exchange rates, and engineering/manufacturing ultra-precise nanotechnology supported by long supply chains of obscure parts and inscrutable RTL/ASM/C code.

If you would like to help decentralize and protect the network, while possibly profiting in BTC or fiat, HashFast can help you do that by selling you the fastest ASICs in the world.
