I have seen quite a number of topics here where people have been selling or asking for advice whether to sell their properties to invest them in bitcoin. Am surprised some people forget that crypto investment is not always a win affairs. You either lose or win. You can as well make profit in crypto with small capital if only you have the patience to hold and wait for the time when the market is booming. Do not be a greedy investor. Always invest with an amount you can afford to lose. Have a nice day.
I don't think it needs big investment in order to make profit in crypto. In my case I do not have capital when I started back crypto business, what I did in order to earn good profit was I joined signature and bounty campaign of a potential project. I studied on how to choose a good project and airdrop last year was very good enough to give earnings thats one also I got earn more. So maybe it depends upon the person who manage his business with crypto.
