It really depends on what coins you want to hold and how long you want to hold them. A good desktop wallet that is easy to use and supports several coins is Exodus wallet. That's a good place to start.
Elegro wallet is amazing product. Best of it’s kind. Once registered, I gain the full package of tools to work with crypto. I also think it is great solution for a merchant who wants to increase his range of customers as many people own some crypto nowadays.
