Just take your time to research on the current market trends and you won't be disappointed at all as you would make profit even in any market situation whether it's bull or bear market. This is the first thing, you could do to increase your portfolio. On the other hand, staking/LP mining, NFT flipping is still great ways to make profits. All you need to just DYOR before jumping into those projects, else you could end up with losses. Also ido/igo is a good way to make profits but it becomes more risky as vesting period is long and none knows what would the condition of the market in the next few months. So DYOR and select any option carefully.
