How do you think Bitcoin will fare in about 3-5 years?

It's hard to say. Bitcoin's recent fork into cash seems to have been a major double-edged sword. A whole Bitcoin once upon a time used to be very achievable, today because of the demand a sliver of a bitcoin is hundreds of US dollars. A lot of it was instigated by the arms race to make miners, especially with those with the sheer amount of resources to do so. If the IRS ever reverses its decision to call Bitcoin currency instead of property, then perhaps.
