On one of the two possible places:
1. Valued over 100k$, widely used, low fees, transaction confirmed in seconds
2. Historically known as largest crash in last 10 years, eventually replaced by some other more advanced coin.
At the rate Bitcoin has been going up in value in the past years, that $100k can be reached in 2 years already.
Of course, that's pure speculation, and given Bitcoin's track record it's very likely to crash hard at least several times.
I doubt a "more advanced coin" will have an edge over Bitcoin: in the end, all you need is to be able to make a simple payment. Smart contracts and all that are solutions for problems that don't exist.
Meanwhile I've set my plan: I sell a bit when the price goes up, I don't sell when it goes down. So far, everything I ever sold would have been worth more now, but at least this gives me some piece of mind if the price drops hard (again).
And since I only sell a small percentage at most, I won't be out of Bitcoins if it reaches a very high value.
I just hope Bitcoin will finally be able to scale up, so it can handle much more transactions, much more users, and with very low fees again. Currently fees are about 50 times higher than my bank charges. That may seem small compared to the price increase, but it's all money lost through miners to power companies and hardware manufacturers.
On a side note, I'm afraid Bitcoin forks are the new monthly hype now. After altcoins (shitcoins) and ICOs, we'll now have to keep splitting our coins on multiple chains
The average fees has always been around 0.001 for most of the transactions
When I joined this forum in 2015, I could make fast transactions with 0.01m
BTC fee, and even zero-fee transactions (with Medium priority and aged coins) were fast.
Since then, fees went up 100-fold in Bitcoin and 3000-fold in dollars.
