I'm here to discuss cryptocurrency wallet . Well, for your information creating a portfolio is not the central aspect but for which purpose you want to create a Bitcoin wallet is the primary aspect, because there are many types of bitcoin wallet like, Hardware wallet, Desktop wallet, Mobile wallet, Paper wallet and some other with their own feature.
If you just wanted to store your Bitcoin, then Hardware wallet or Paper wallet is most preferable choices. They come with the best security. They are used if someone wants to purchase some (healthy amount) Bitcoin and store them for a very long time like many years. If you want to trade Bitcoin, then use a wallet on any Bitcoin exchange to trade your Bitcoin like BTC dot com wallet or bitcoin wallet. They are least secure because technically you do not own your wallet, a portfolio is on their server, and they handle it, you only take request. So choose very carefully. So it is up to you, for what purpose you want to create a Bitcoin wallet. Hope you got your answer.
