I believe they will be the first switching over to Bitcoin and precious metals if fiat and financial markets go down. Big investors, global companies, hedge funds are the ones who will be first.Just alone this could create crazy spikes!
My biggest concern would be if the network could handle all that in a very short time.There's a lot of work to do and we can not waist time.
Just alone the halving will create another big media attention I believe, which could trigger another wave of new participants.
That is why it is so imperative that the Core Dev Team / Miners / Exchanges get through this existing Scaling hurdle. There are a lot of people watching this and saying, these people simply do not get it...... this financial crisis could happen fast. Again, NOT saying it will happen this coming week, and I am not quite ready to declare we're at the beginning of a huge liftoff - but if Bitcoin recovers all the way by end of weekend from the 13% triple smackdown they just attempted, then I say odds are that we just got a lot closer to liftoff.
I think things are growing at a good pace, the last convention was a success with the presentation of sigwit, so we are making progress. We will be able to scale before the average joe catches up and the transaction volume skyrockets, we are still at least 1 to 2 years before the average folk jumps in and that time is exactly what it take for the lightning network to start scaling it to worldwide levels.
And as it relates to the topic of this thread, a pretty good Bitcoin Investment Series just stared running at Forbes.com. This thing is getting ready to start moving faster. 1 to 2 years. That is just plain stupid. I don't care if you want to put your faith in a Lightening based scaling solution - but if the basis of the timelines for those plans is beig made by people like you - then Bitcoin is in S#!t trouble.
