Can this shitcoin sitting in my wallet somehow extract the rest of my tokens? I just made a new MEW and still have that INSP in there.

If we stay away from all kinds of ponzi schemes like scam ICOs, then swinging btc and alts would be best. When btc has news to grow, buy btc, when btc is about to have a correction, buy alts. Rinse and repeat.

Well, banks would still take from people as much as they can. They will force governments to regulate btc, this would make the currency just another asset they can control. End of story.
