If we continue to have these fees and long transactions times, I think bitcoin wont stay #1 for long.
I've found myself questioning this exactly. It seems like people use other coins to actually spend, leaving bitcoin's use to a wealth storage tool. I think bitcoin will need some updates soon.
In my opinion i think bitcoin will remean a leader in a crypto 50 to 100 years that was my prediction base on the capasity of users enrolled. If somebody one of cryptos surpass bitcoin being bitcoin is slowing down to the last drop. Will thats the sign of bitcoin era has ended.
