Legendary investor Bill Miller expressed on CNBC on Friday he perceives Bitcoin flowing 100% in 2021 as more investors add the coin to their portfolios as a hedge against inflation. 

One of the things that's exciting about Bitcoin is that it gets less risky the greater it goes, and that's the contrast of what occurs with most stocks, the Miller Value Partners originator said. 

He added that he's not certain when the value of the cryptocurrency will be exact, and if investors aren't set to stomach another 80% alteration, they possibly would not own Bitcoin. 

Miller does not have a charge target for Bitcoin but supposed he has "price expectations." 

Bitcoin has more than doubled up in price over the last month and raised over 30% in 2021 so far. Though some Bitcoin investors need to make returns off the table currently as the price balloons, several investors who have not bought in yet are to come for a rectification so they can purchase it at a cheaper price.

But Miller said investors who are waiting for the pullback that previously happened in the first quarter of last year when the value floated around $4,000. That's what usually happens. It is that once things are accurate, those who are waiting for the improvement- they are waiting for the correction to keep going lesser, Miller said. And then when they lose it on the upside, they are asking if they would buy it. 

We have had 3 80% alterations, I think if you cannot take that, then you possibly should not own Bitcoin, he mentioned. 

The investor seemed on CNBC days after printing his fourth-quarter market note, where he said that Bitcoin is "best believed of as digital gold", but has a number of rewards over the valuable metal. This rat poison can be the cash with regards to Bitcoin.
