Few years ago bitcoin is very cheap and first it is used to purchase pizzas.
2years back it is nearly $800 today nearly $12,000
After 5 years I strongly believe bitcoin a digitalized crypto currency price go more high where we can't purchase bitcoin due to scarecity.Bitcoin is a trend setter for other Alts to my view
You know 2 years back bitcoin was not $800, If you remember that in 2016 bitcoin was $285 to $300 and it was a start of 2016, then may be you have mistake. But it is right, after 5 years bitcoin is like a demand and it will has a highest price, and not everyone can buy bitcoin easily.
