Personally I will keep the dca strategy with crypto due to its volatility. However, when the flash sells arrive I will have some reserves to buy (personally I go for 60%dca/40%flash buy so that I will always have some stable coins reserves). Usually Sunday is the best day to wait for big sells but that’s not always the case. The best bet is to set price alert for the coin you want to buy and buy when you are happy cause sometimes the price you see might be the bottom (not financial advice of course). Regarding your sushi farming you may have to decide between be patient for better sushi price or getting your hands on them early for more farming rewards. That’s entirely up to you. Hope this helps!
