Sometimes people need to understand that trading is not good for a source of income, you cannot make a consistent profit from it and you cannot predict the entire market. If someone asks me how profitable trading is I won't answer them because I know not all the time you will increase your portfolio. But instead --you need to level up your experience which even experts cannot avoid losing from trading. So increasing your fund in trading depend your experience and knowledge.
it is all caused by the high risk of crypto trading. so if you want to start trading with the aim of a source of income it is not recommended.
how many people have suffered big losses when trading without good knowledge or experience and just want to get profits for their daily needs.
but if you do have good experience like OP who has been trading for 4 years and wants to increase trading and profits by doubling profits over several periods so that more funds are collected after that you can look for daily profits as a source of income
One way is to spent money to get money because if you spend cash then if optimum situations arises then it will get up high and your money will be elevated as an outcome of this but do not follow other fellow as it can lead you to the wrong path. Put money differently in different coins which are successful and you hope that they will elevate so you can raise your fund.
What do you mean spend money to get money?
in the strategy of getting profits every trader has a different way. by buying several different coins to optimize the risk is not easy. usually a trader will choose one type of coin to be used for trading for a certain duration to get daily profits.
so taking a few coins is not the best way
