It would be a case of trading some BTC for ETH. I had thought of doing that when ETH was around $1700.00 but didn't. Sigh.... But ETH and DOGE are around all time highs (ignoring the fact that they are down a bit today), and BTC is down, so it doesn't seem like a good time to do anything.
When there is a downturn in BTC and some Altcoins, it is actually a good time to net all the popular tokens at the lowest price, I believe moments like now are moments to get more profit when these corrective conditions can be finished in the near future.
Definitely right, with that downturn also makes you get those popular tokens because of the lowest price it has. Talking about the percentage of investment between btc and eth, I will choose the same percentage to both, because both are good in gaining profit. Downfall is just normal which we don't need to worry. We cannot stop those things because it is a matter of how demand it is or not.
