Some of the whales you think are bearish will soon be bullish, the downtrend in price that you are noticing could be what would start the next bull run. The price is low already, just buy and forget until the the price rise, 1 bitcoin is 1 bitcoin.
I continue my weekly DCA.
I have a comparable strategy. At 50k+ I was only spending everything, but doing it slow to benefit from possible long term bull market and 100 thousand dollars.
When we came below 30 thousand I started to accumulate slow, doing some DCA with the money I had on my exchange accounts.
When we went below the psychological level of 20 thousand I said to myself that I'm not throwing away bitcoin this cheap. I went into heavy, constant DCA using only the money that I need to pay the bills every month and spending all the rest on bitcoin.
I don't care what the whales are doing. There's a reason why the time we're in is called the accumulation phase.
The time to sell was in distribution. If you managed that you made some money.
