I would invest in both, lightning is solving a lot of problems with BTC and ETH is still not in it's final form, I would also invest in new projects because in the long run...
The vote for sure if half.
Other believe better to buy bitcoin because the price already decreased more than 60 percent.
Other people believe better to buy ethereum because it is next bitcoin because of they a lot of project now.
So if you can't choose any of this coin better to buy both.
