If you have a modest amount, let's say $150 a month to invest, here's a mindset to consider:
Maximize Risk-Taking:
Go for meme plays x10 or x100, or even lose it all. Take huge futures leverages. In the worst-case scenario, you might lose everything, but if you win, your $150 could turn into $1,500 or even $15,000.
You have made a very good list and opinions (atleast according to your standards); while you seem to be a cheerful investor (without daring consequences); i have some notes and suggestions maybe you can learn from then. A true investors does not maximize risk taking; instead they focus on how best to increase their capital by investing in (quality) projects, products irrespective of it being a meme or not. Your first question should be; is the project a rewarding one?
If you lose everything; can you call yourself a trader?
Full-On Portfolio:
For you, diversification might not be the key. Go all in on a project. With less money, you need to make a big impact. Going all in could be a life-changer.
Theres nothing wrong on going all in on a crypto project; if it falls in the category of BTC or ETH; because those top guns are here long term. If you go all in on a meme token; it is a bad investment advice.
Farming Airdrops:
Rolling rewards are also quite smooth. Focus on L2 Ethereum solutions.
WORK to Earn:
Find ways to increase your income. If Grab/Ubers isn't enough, go do some grunt work or community management. Maybe you'll make $50/month and chuckle about it.
It is alright to get remote jobs in the crypto currency space; you should use your earnings to improve your trading skills by learning; not by aping every meme token you come across'; remember the better your skills, the more the knowledge and your understanding about crypto currency trading.
Retroactive airdrops are also good, but it is not trading; because you are using the l2 protocols to farm for engagements in hope for reward; and not to buy or sell assets that could better your trading decisions. You need to work onn your trading decisions.
