How bad are funding rates when holding a BTC short for months?

I’m considering opening a BTC short around 85k with a higher timeframe view (possibly holding for a few months if the thesis plays out).

What I’m still confused about is funding rates over long periods.

I know shorts can sometimes get paid during bullish conditions, but during bear markets/ranging periods funding can flip negative and shorts start paying. For people who have actually held BTC shorts for months:

• Did funding end up being a big deal overall?
• Did it noticeably eat into profits?
• Is using dated/quarterly futures a much better option for this type of trade?
• And for platforms like Hyperliquid/Binance perps, how bad can funding realistically get over 3–4 months?

Trying to understand the practical side before committing to a longer-term position.
