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.
Memecoin is highly volatile and I don't think it is suitable for a novice trader. Because when memecoin is pumped, it is huge pump, but when it is dumped, it is huge dump. If you can't enter the market at the right time, there will be huge losses. So I think it is better to invest in top altcoins like ETH, ADA, BNB.
