impossible to remember password, but i am sure it was using symbols , something like "!!!Bicointalk?!##"

how long would take to crack password like this !!!Bicointalk?!## ? or i must wait 30+ years for quantum PCs ?

Not possible if you have to brute-force all 19 characters. Here's the rough calculation following detail,

7 symbol character which need to be brute forced.
There are 33 symbol character on ASCII format.
12 lower/upper case and number character which need to be brute forced.
There are 62 symbol character on ASCII format.
1 (One) Nvidia RTX 2080 Ti. Speed data is taken from https://btcrecover.readthedocs.io/en/latest/Usage_Examples/2020-10-06_Multi-GPU_with_vastai/Example_Multi-GPU_with_vastai/#performance.

Total possible password combination = 33^7 * 62^12 = 137498466041845301308233639923712 (about 1.37E32)
Speed of RTX 2080 Ti = 6.4 kP/s or 6400 password per seconds.
1 day in seconds = 60 * 60 * 24 = 86400 seconds.
Brute force time (in days) = 1.37E32 / 6400 / 86400 = 2.47E23 days.
