The first thing I will say is, "Welcome." It is a is a pleasure to see you again!
 

Anyway, let's come up with your Question?
 
There are a lot of good wallets that have strong privacy. But it depends on you that which of them you prefer. Like Hot or Cold.
 
I think if you want to invest in Bitcoin that I will strongly recommend it to you that ColdWallet be the best option. And the best wallet for cold wallets is Electrum. Which I especially recommend to every buddy who is not much related to Bitcoin, meaning new and inexperienced. Electrum is the best for bitcoin holding and interestingly, it has a very easy and friendly interface that is easy to use. This wallet is only for Bitcoin; besides, it has the security feature of multisig or cold storage. 
 
It is your choice to use what you think is best. Because no one is responsible for loss or profit in the Crypto industry. DYOR!
