Hence why they have yet to certify doge. The fees are higher but you can also setup the professional app.
Buy ETH. Bitcoin may come down more to around 45K-50K so wait (or maybe it already is bottoming). Buy smaller incremental amounts to scale in. You can set up reoccurring deposits if you want to.
Stellar Lumens and Algo are my speculative ones (small positions). Algo pays 6% apr in coin rewards. They’ve done well but are currently correcting with Bitcoin. Most coins not named doge actually have a high correlation to Bitcoin price. Doge is hype but people keep buying in?
Fwiw you may be 6 months behind getting the good prices. Or maybe Bitcoin will be 100K plus (double) by end of the year. These are volatile assets. In theory they should continue to rise as they become more accepted and investable. They are basically digital gold/assets, especially those with supply caps. Potential Government regulations poses some risk if and when implemented.
