Maybe back in the days where you could earn from the faucet and other things.
But right now I don't really think that you could start in crypto with nothing.
I agree. By "nothing", I meant nothing as in you can't start right away. Even when you have money, you still can't start earning bitcoins right away. You still need knowledge and I really think that it starts and ends with knowledge.
You can start trading with your money but you can't just buy an altcoin, cross fingers, and hope for the best. You need to understand why is that coin good to buy and why other coins aren't. Even the usual signature campaign, which is every newbie's favorite crypto making method, requires knowledge. It's quite hard to start with crypto these days but everyone wants to jump to earning money from it. It's not like they can digest all of the concepts and ideas behind it in just one sitting. It seems like an easy job, but it's only easy if you know what you're doing. In the start, you're going to have a hard time getting the hang of it as it requires tons of research.
And yet that is something that a lot of people do, they have the money but they do not have the knowledge to make money in this market, however since they have heard so many stories of people making a fortune then they think that something similar should happen to them and they just invest in whatever coin that they see hoping for the best and we know how that ends.
