First things first. This is topic is not to create a FUD rather a true talk to what is happening right now.
Can bitcoin get a hold to its investors to stay on him and keep believing on the power of the king?
For me, I can feel that investors are now turning their back against bitcoin because of this main reason. Tx Fees are very high and slow. It is not practical to be used on daily transactions which I think the first purpose why bitcoin was created.
I think, what you say is true. is there a solution for this? to reduce the value of transaction costs and the delays that occur most often. this is a problem we must solve together.
