I have read two good advice in the topic, 1. GET A JOB, and 2. SAVE MONEY. If it's possible in your situation, it's also good to get a second job, ANY job.
I know nothing about fundraising so please guide me through this process for my better future.
It depends a bit on the amount of money you are looking for. As a successful trader it should be easy for you to convince potential investor to give you some money.
"A successful trader"? It's going to be very hard to convince anyone with only four years experience to give OP the money for him/her to gamble. Would you give him/her your hard earned money because he has four years of experience? I believe there's a high probability that you can outperform his/her portfolio by simply HODLing Bitcoin bought during the bear cycle, then HODLed through to the next bull cycle.
