Is not my case, I do have some savings so I didn´t start from absolutely nothing, but I had not much to start with. I am having a decent go at cryptos and I think it may be possible to make a living... What could be a good strategy?
Yes, starting from zero, not investing your money is quite possible. You can start with airdrops and campaigns in social networks. From there, the initial means for investing will appear.
Starting from zero is completely possible but the problem is that the market is not going to remain like this forever we need to get as many coins as possible and if you don't then you could miss the chance of your lifetime when bitcoin and cryptocurrencies skyrocket and reach prices that we can only imagine right now.
