Is there one wallet for all the different crypto?
Before you know it, as a starting crypto investor, you may have different cryptocurrencies stored in more different wallets and exchanges than you would actually like. After all, it is not ideal to have all those different passwords. Moreover, from a security point of view it is also not recommended to store a large amount on an exchange for a long period of time.
Unfortunately there are no wallets and exchanges that support all different cryptocurrencies. New cryptocurrencies are added daily and at some point you will no longer see the wood for the trees because of all the different wallets that come with them. This also does not contribute to the adoption of cryptocurrencies by the mainstream. See also Bitcoin Revolution for more information.
