If I were you — trader / passionate / visionary crypto — here’s how I would allocate my assets on Binance in December 2025:

• 40-50 % in BTC (security + stability)

• 20-30 % in ETH + 1-2 solid altcoins (SOL, XRP, BNB)

• 10-15 % in stablecoins (USDT / USDC) for liquidity, to seize the dips or secure part of the gains

• 0-5 % in riskier or new altcoins — with the goal of "potential x2 / x5", but accepting the total risk.

It’s a mix of security, diversification, and opportunities — which fits your profile (investor + active crypto + taste for controlled risk).
