New here, question about position sizing for smaller accounts

Hey everyone, just joined. I've been doing some demo trading and paper trading for about six months, and starting to put real money in. One thing I'm still wrapping my head around is effective position sizing for smaller accounts, say under $5k. I know the standard 'don't risk more than 1-2%' per trade, but when you're looking at things like $SPX options or even some of the higher-priced cryptos like $ETH, that 1% often means you can barely afford a single contract or a tiny fraction of a coin, making scaling really difficult. How do you guys approach this without either overleveraging or just getting completely sidelined because the numbers don't work out for meaningful position sizing?
