Binance futures vs Margin

Hello everyone,

I'm relatively new to the scene, like everyone, I made lots of money some days, lost lots others. I'm currently looking into futures and I'm wondering if there's a way to utilize futures the same way we can utilize leverage tokens (such as ethup). With leverage tokens in the spot market, it varies between 2-3x and I'd like to increase that leverage to something close to 4-5x without having the liquidity aspect of futures. Is there a way that I can buy 500$ worth of any perpetual crypto and even if it drops by 10%, I don't get liquidated, I keep my position? I'm starting to understand that COIN-M futures a certain amount of assets to open a position if I'm not wrong, I assume its the same for USDS-M Futures.

Regarding Margins, I believe I understand the Cross vs the Isolated differences. IF, on my binance account, I have 5000USDT in BTC for example, in Cross margin, I believe the leverage rate is locked at 3x if I'm not mistaken. Thus is BTC goes up 3% from my initial investment of 5000, I should be up 9% on my investment? I'm just trying to understand if Futures can be used as a stronger version of the Spot leverage tokens.

Thank you in advance
