Stay away from equity shares.
Equity shares will the first ones to be deemed as securities.
If the SEC deems that the altcoin is a security, that altcoin will go to zero or crash minimally.
Buy an altcoin that has a function. Bitcoin has a function, as it is used to transfer value (currency) or store value (like gold). Your ownership of one Bitcoin doesn't represent ownership of anything other than the one Bitcoin. Firstblood or Kik serve functions.
Coins that sit on a spreadsheet to determine your percentage share of the equity, profits, dividends or underlying assets (real estate, other coins, etc.) will be the first to be deemed as securities.
