Monero would be a great investment, it's a lot more secure than Bitcoin plus it outright banns AISCs so the growth doesnt go trough the roof followed by a crash, it's a rather stable coin that is growing, that's my 5 cents.

It depends on what you plan to mine and the prices of power in the country you'll be based out of, I'm sure there are IT subsidies that you could apply for that could fund the project, I'd suggest first doing a profitability analysis and checking your local legislative if you'd be allowed to spend the subsidy for creation of a mining rig, solar panels etc.
