-Bitcoin wallets ((("wallets", "choosing")))((("choosing", "wallets")))are one of the most actively developed applications in the Bitcoin ecosystem.

However, we can categorize Bitcoin wallets according to their platform and function and provide some clarity about all the different types of wallets that exist. It is worth trying out several different wallets until you find one that fits your needs.
