>> Anyway, is there any alternative to DigitalOcen (free or cheap VPS or dedicated servers)

all judgmental notions aside, I have to agree with the other poster that
spending some time looking into this would be wise before launching into it

Why would anybody, anywhere, ever provide you with free profit?  the answer of
course is that they won't. If you spend money to mine, you will be taking the risk
that future gain will provide your return.... or perhaps I am the one being naive, since your
technique so far has yielded 0.3 btc with no actual payment on your part.  perhaps you
can just rinse and repeat and hope you never get caught (ok, a teeny bit of judgmental language)
