When the market is sluggish, the coins you hold should be mainstream coins with strong consensus. Every time the market picks up, it's always these coins leading the rally, not the low-market-cap coins that swing wildly without any consensus. Chasing a big win occasionally often results in losses when the market turns, and the account value doesn't actually increase. You need to develop the ability to quickly identify which first-tier coins to buy when a major market rally comes, instead of being drawn to heavily manipulated small altcoins.
