I have two coins that use to increase my income in my investment, which are Bitcoin and Ethereum and whenever there is a bullish season, there will be surplus income in the market for those that have coins to sell in the market. Whenever I make income from the market, I will save some against the next bearish season that will take place after the bullish season that use to give investors opportunity to purchase coins from the market and hold for a long time before they can sell to make income. Using the income to invest in other investments is very important, because if anything is happening to the coin you are holding and you don't want to release the coins for sale, you can use other investment income to solve the challenge and continue holding that coin that will bring passive income to you in the future.
