I don't how you define high volatility, but if you mean 30-70% daily (or more), then you should start with new coins that enters the market, specially meme.
Agreed, the high volatility coins are not the ones to be looking into. Indeed these will be newly launched coins and usually these get massive dumps after all private investors get their tokens unlocked. Not recommended to invest this way. Volatility greater that 40% is a no no... At least that's my approach anyway
