taking part in airdrops, bounties and sigcams is a way to get free money but not sure. because if you look at some of the airdrops, bounties, etc., there are lots of scams and sometimes the results are small.
whereas what the OP wants is to earn more money to increase his trading. so airdrop etc is not a good solution.
OP said he traded for 4 years and wanted to increase large trades with the condition that he had a large capital and OP asked for a solution for how to get bigger funds to trade at a bigger level.
but you say collect funds from trades, maybe you mean collect profits from current trades and multiply the profits on trades.
it's not that easy when traders don't have good financial management and strong commitment, it won't work. because lots of traders often skip this stage and can't progress to a bigger level in trading
