there are lots of ways to earn cryptos. there are bounties, airdrops and mining, all of which you dont have lots of investments just effort, surely you need high end computing powers to be able to mine but you already have that if you are into gaming. when you have enough you can do trading where there are lots of risks but higher returns, hence, you dont need lots of money, you need effort instead. Having big investments however speed up the process so its up to you which would you prefer, less effort but more investment or less investment but requires more effort?
