i tried to calculate how much would i make from bitcoin mining using an antminer s9, and i don't think it's worth it for me as the cost of electricity is high where i live, which is in the UK (it's 20 cents approx), i make like $300 profit a year. and obviously i can't use faucets as that will take years to get one bitcoin. so is the only way to even get any value from bitcoin is to buy it and hold it on for another few years? but it is a risky investment due to the price. or should i invest in new currencies that are cheap right now and have potential to grow to $4k a coin? 
Yes, its the easiest way to buy bitcoin if you have fiat money.
But there are other ways even without money to gain bitcoin.
Like joining a bounty campaign. One of the best way to gain bitcoin without any risk at all. The only thing you have yo do is to finish the campaign till the end without violating its rules and regulation.
Now,if you have bitcoin, its a good investment if you buy alt coins and hold it for a while until its value increases.
