The price has risen over 25% in the last 30 days. It is a good performance.
Not just in 30 days.
It has been risen for 100%-200% for the past years. Look at the price history and we can see the tremendous rise even lots of price decrease happened.
The simple logic behind this must be doubling from $1 to $2 is not taking much time but from$2 to $4 will not more time and I believe this is what happening now.
As you mentioned bitcoin as showed many tremendous appreciations in short time periods still I guess the recent surge must be a a good one. There will be no wrong to acknowledge this as one of the spectacular bitcoin performances.
