yup! i think that's a pretty good idea.
i will do as you say, at this time part of the altcoin that i hold i have sold and bought bitcoin.
and now i only have bitcoin, BCH and ethereum in my wallet.
i hope the market will pump up and end this frustrating period.
It feels like the period of falling prices for altcoins will never end. Its good that although Bitcoin behaves more stably and predictably, you can invest in it without fear. Perhaps we all will have to hold many altcoins for a long time before they give any significant profit.
The lesson here in the bear market especially when it comes to altcoins is, only buy the altcoins that are strong enough and good enough for long term holding. So even though their prices will still plummet, you are still confident that they will have a comeback in the market and they will give you a lot of profit in the future.
