OP, I'll try to be on topic and not direct you to buy coins with the money 
The question here, which I hope you already calculated, is have you turned a profit? If you have, that's good, you know what you're doing.
Since you were saying you have started mining with GPUs at the beginning of the year, you probably know already that ASICs are not like GPUs in the sense that they will probably become obsolete (or how these guys here want to call them: "door stoppers" ) and you won't be able to use them anymore for mining once the algorithm for your target coins changes.
In some cases, ASIC manufacturers announce their new ASICs when the most profitable coin states that it will change the algorithm to be ASIC resistant (see the Monero & Baikal case study).
If I were you, I would research more in the FPGA market rather than ASICs. FPGAs can be programmed to work even if the algorithm changes but you won't have the same hashing power compared to what the ASICs have.
Hope this helps
