Exactly our point, a 3rd party WILL eventually produce faster hashing chips and cheaper ASIC's and build their own mining farm if mining this becomes profitable, the race to becoming the biggest mining operation
If it happens sooner then later, there could be the possibility of not getting a return on your investment either.  I remember when guys were buying ASIC miners for Bitcoin, by the time they received them and started to use them after waiting for backlog and delays from manufacturer they were already at a loss on ROI of their purchase because the difficulty rate increased with all the ASIC mining activity too quickly while other 3rd parties had already developed and were mining ahead of others with  faster hashing ASIC's with better power consumption reducing costs and were already mining for themselves ( they were paid for pre-orders and used for themselves to self profit ) then they ship them late to their customers, and repeat the process once they develop faster ASIC's while always making profit.

I know you can't possibly control how other companies practice but anything that can make a quick profit will encourage greed which will lead to an unfair monopoly. Safest play would be to just buy as much siacoin as you can now while it's cheap if you believe in the project to be successful rather then taking the riskier road to ASIC mining with cloud rented or purchased ASIC's, the little guy always loses out its been proven with all ASIC mining coins once the big players take over which sadly happens.
