In the past, Ethereum was always the number one choice for new ICO projects but now there are almost no projects using this coin.
I don't have any idea what another choice would they have if they were to invest in ICO projects. I know almost all of them are ERC-20 Tokens.
I think it is difficult for ETH to return to the highest price level because the current investment demand is still very low and bear market is making this coin worse. In my opinion, it is best to hold fiat or stable coin because this coin will have more adjustments before starting to increase in 2020.
That's basically what I said. It could be caused by different factors, not just Bitcoin itself but the best thing to invest in, IMO, is still BTC. What stable coin you specifically are talking about?
Of course, this is just my prediction and ETH will depend a lot on the value of Bitcoin so wait patiently and consider investing little if you feel this coin is cheap.
If you do this, you would be averaging your bought BTC every time and it's a good idea if you have the spare money.
