Based from the experience on my friend, first is bitcoin then next is ethereum. I say he has a lot of patience because she managed to hold her earning (bitcoin) last 2017 or 2018 up to now then hold she sold some eth last year and still on her wallet right now. Although she hold small bitcoin and sold small amount of eth, it is still a good investment. She holds because her reason is she can't buy or own bitcoin once more if she sold it already. She also believes that bitcoin will grow more so she will earn more.
