Alternative to strike?

TLDR seeking best wallet for small investments routed to cold wallet, with low fees, that's super easy to use, and that does bitcoin and ethereum.

I like strike. I will say, they do seem to squeeze the prices and the no fee seems to be mildly expensive, not free. But on face value, I like the simplicity and I like the program, and they make it easy to chip away at bitcoining.

In any case, I have more than .00004 bitcoin now, and so would like to diversify, just slightly (that's a joke). Ie, dividing into multiple cold wallet accounts rather than one, maybe setting up multisig, etc.

But it doesn't seem bad to invest in ethereum (just being interested in diversification for risk management)

For small amount purchases with the goal being to route stuff to cold wallet storage, any contenders with strike? Again, not making purchases over $10,000 us, or over $1,000 us. Don't care about speed (strike no fee transactions that take a while are fine for me), but I do care about margins (why should i give up 3% of my thirty cent investment??).

Thoughts?
