Why would I want to keep BTC in my investment portfolio? That's most hyped and quite overvalued coin I'd say.
There are other more technologically advanced coins. Is it because of "digital gold" and store of value properties?
well bitcoin is a good investment so many bitcoiners know that and why we hold bitcoin for our future? is because for family you future its can help you for your future and because bitcoin is a good investment and its help a lot its help you for your needs
For me, keeping a bitcoin is the simplest way to both save and make a profit on that investment. The thing you need to do is extremely simple, choose when the market is going down and buy in bitcoin, though more or less if you keep your bitcoin it is still a great investment for the future. I think you will never regret for investing in bitcoin.
