You swapped all of your ETH for BTC? I feel like you shouldn't have done that. Not all of it at least... Diversifying isn't bad
And now that Ethereum is average declining unlike Bitcoin in which it dominate the crypto market of up to 70% then maybe they will now regretting it and will think that they made a mistake. So better if they just sold all of their Ethereum directly to Bitcoin as this coin is proven safe for both long term and short term investments.
