Personally I don't want to judge you, but my curiosity went up while you said if you focused on micro task (airdrop, social media, and youtube bounty). Because when I compare to your account, seems your account is not active in Bounties, only
1 airdrop and 1 youtube bounty

Back to your topic, That's true you should avoid all HYIP investments. And you should avoid long-term investment on altcoins, because altcoins is for short-term or mid-term only. It's very risky and not recommended to hold altcoin for long time. Bitcoin is the good long-term investment.
