Is it still necessary to increase the position in Bitcoin?
Personally, I do not recommend it at the moment.
Unless it spikes back to around 66,000. Although this situation is very unlikely.
However, there is still a chance for Ethereum, even though it has reached 2,800 USD now, it's worth noting that Sun's holding cost is at 3,100 USD.
Moreover, next year, Ethereum is very likely to reach 7,000 USD, which is about a 3-fold increase.
