even with the reduction of the block reward I still think that the number of coins created per day is very high.
The dump will be greater after the FPGAs are widely used.
Why should the "dump" be higher? Even if billion of FPGAs are used, the total amount of mined coins will be constant and decreased with each block reward reduction.
Yes, but electricity costs will be much lower with FPGA than GPU, so miners will be more willing to dump
FPGA's have much more up-front investment cost than a GPU and FPGA boards are now all sold out due to a 3x price increase in the LX150 chips. So the sold out 350 Euro ZTEX 1.15y would now cost ~1050 Euro if they were to manufacture more but they have stated no more will be produced. There are many factors on multiple levels to consider.

Thank you for your support.
