For me when bear market start trading pair switch to alt/usd and scalp trading or buy when dip happen. When bullmarket start switch back to alt/btc. Keep in mind many alt will dien when bear market hit, even exchanges will gone with customers fund, last cycle most altcoin only pump 2000% same as btc did, so whats the point holding alt, that depend on your strategy when trading alt/btc or alt/usd
