I thought for sure it would take until the end of 2018 but it looks like this summer ethereum might pass it up. With the turmoil around BTC potential splitting, it might be very soon. IMO this is healthy, we will always value bitcoin for being the one that started it all, but it's time for a more dynamic and adaptable currency to take the lead.
Well I think that thing is quite inevitable wherein no matter what we do, we cannot dodge the incoming threats that may bring bitcoin down. In my opinion, if we really want bitcoin to stay on top for a long time, we should atleast keep on supporting it and avoid spreading false news about it. We can help bitcoin through the little things we are doing. Let us keep our hopes high for bitcoin and it will surely give the desires of ours.
