The cost of bitcoin transfers has increased. Do you think this is trivial? Is it worth transferring money with bitcoin? Why transfer money with Bitcoin if the transfer cost is high?
like i have 100$ in one of my old wallet but i cant transfer it because of transfer fee is more than my asset !
Depends on what wallet you are using, you should have told us. Electrum for example, will give you the options to adjust as how much fees you want to used. Maybe the wallet you are using as from some exchange that you don't have control of the private keys and the fees obviously.
Lol, you should have been here during 2017's run wherein it will take days if not weeks to be able to transfer bitcoin because of the high fees. That is one of the worst, but today you can even transfer in less than a dollar.
