For me, it's always a yes. As Bitcoin got the highest market cap in the crypto market now. But some people may advise you that if you will invest in Bitcoin, you may get a low ROI.
So yeah, it's still up to you. What my take here is, if you want low risk, you expect low reward too and opposite; high risk: high reward.
Not everyone can afford to invest a huge amount in bitcoin. The price of bitcoin is quite expensive. All fingers are not meant to be equals.
Buying a portion of bitcoin will not be assumed as taking low risk rather it's a step to richness.
Investing in cryptocurrency is the best investment so far that has come into human existence
