Then the best move to get a higher ROI in staking would be to buy low now, HODL, and wait for periods of high market volatility before buying tickets, more preferably during a bull market when holders stop staking, and start trading.
I disagree. If you're waiting for the lower ticket prices, your potential ROI is dropping every day, because your capital simply isn't working. So if you wait long enough, your ROI is gonna be lower, than if you used a standard auto rebuy strategy. The average ticket voting time is around 28 days and one can hardly call Decred an actively traded cryptocurrency, so, basically, you can wait for a couple of months before that high market volatility that you wish for finally strikes and you're finally able to get the tickets at a low price. In the meantime, the one using auto rebuy strategy buys new tickets regularly and in two months period, most likely almost all of them vote twice. Actually, you can check it out for yourself by setting up two separate DCR wallets, applying two different buying strategies to them. You'll see which one performs better.
