bitcoin is indeed much expensive right now when compared to etherium but you can still be able to buy it on a smaller amount or units of satoshis/mbtc because they are still valuelable and have a big worth even though they are just dust or chunks of a whole bitcoin. you can then add on some etherium to your current holdings because etherium is still continue to grow just like bitcoins therfor it should also give you a stable descent income if bitcoin could fall back down on  some times.
