When it comes to Ethereum or Bitcoin. It's not a matter of whether you should buy or not. It's about 'when' and as the market is going down, It's definitely a good strategy to accumulate more.
I agree with your opinion, I also decided so, this is also an opportunity strategy for those who will gather as much as possible.
I see a lot of people waiting when it will come down, because of their chance to collect, and they wait until prices soar.
