Not sure what do you mean by surpassing.
Surpassing in dollar value? I dont think it is possible as the coin circulation is so huge for ripple and it keeps on increasing every month. It is kind of limited in room for growth. As many might not aware, for the next 55 months, upto 1 billion xrp will be released to supply for institutions from the locked up escrow. So every month the coin count will increase by upto a billion which is going to make growth slower
The only possibility i see for this happen is bitcoin drops to single digit. Which i think is impossible for now.
Marketcap
Again, the huge increasing supply. But this has higher chance to happen than the previous one. As bitcoin has a low supply, if bitcoin price drops below $5000, xrp would easily be above the btc marketcap.
Usage
Yes. As xrp is primarily used by banks, it is highly possible that the number of users/transactions would be higher in ripple than bitcoin.
I strongly believe most investors in ripple dont know the difference between the following
- Ripple — The company
- Ripple Network — The underlying technological framework for transactions primaryly using USD, Eur and XRP.
- Ripple the currency aka XRP
Most people believe that any news related to ripple is going to increase xrp value. So it is heavily overbought at this point of time.
