If source of income is a problem, then you are not good to go in to trading. Trading is not just about having capital to trade, the market is risky and anything can happen to your capital and if you eventually lose how do you intend to continue with the trade?
Are you saying without source of income trader will not make it from trading? I have seen many traders who became successful in trading without having sources of income before going into trading that is attracting other traders. I will not deny the fact that it will take some traders without no source of income long time to achieve their goal from trading.
Apart from newbies, I don't think there are traders who don't know there is a risk to take in crypto trading, because the moment you enter the market to start trading your mind will surely remind you the risk you are taking and you will not blame anybody for anything that will happen to you.
People who have a better experience in trading quit from their job to become a full time trader and they have trading as the only source of income. It is not advisable for anyone to trade without having a source of income be it experienced or beginners because in trading anything can happen, and if anything happens you always have source of income that you can always rely on. Trading is very risky and you can't predict the market, because of this it is not safe to rely on just trading.
It would be a total suicide if you would be quitting your job directly even if you saw yourself that not still profitable with trading. Come to know that it would be that taking up for some long time and tons of efforts on which this isn't something that can be achieved in a shortened time. That's why it's recommended that you should be making it first as some sort of side income aside from your main job. Never rush up yourself on trying out to go full time if your skills isn't that enough. Always be that having that realistic approach and treatment rather than on making yourself delusional.
If you are planning to touch up trading or any investment out there then you would be needing of course to have that capital on which you would be needing up to start up. Come to think that when you are just that starting up then you would be experiencing those loses and if your budget or funds are just that limited then how you would be making up that deposit to try it again? You would be having that cut off learning because you cant be able to sustain anymore and its a very wrong kind of mentality if you are just that trying out to have that kind of approach on which you do believe that you can be able to directly having a direct grasps when it comes to trading skills. You would be needing up of course to have that source of income for you to be able to sustain and would be able to provide when it comes into the time that you would be losing up money. Its important that you would be thinking up with these kind of considerations. The only bad thing on where people be doing is that they've been that believing that they can be able to find themselves that able to learn trading and thinking that they can be profitable after than. When reality do slap into their faces then they would be having that kind of realization that it was never been easy and never been that possible on which if they would be having that kind of approach towards trading without having that source of income.
