You should be specific with your question, what do you mean by obtaining? is it by mining, buying, or working for it? Obtaining Bitcoin is very easy, by just buy it on an exchange then you can instantly obtain some Bitcoins but of course the price is not cheap but you can always buy any amount you can afford, when it comes to mining Bitcoin it is also hard to obtain because of the mining difficulty, meaning there are lots of competition, in this case other cryptocurrency is more easier to obtain because there are only few miners but the profitability is not guaranteed. If you will work for it, it makes no difference by earning cash or fiat, you will just provide a service or work then you will get Bitcoin as payment. There are cryptocurrencies that can also be obtained easily by an airdrop.
