If you consider the amount of commission for the transfer of BTC in dollars, it turns out that it depends on the cost of the bitcoin itself, and it becomes obvious that when the BTC is expensive then the commission is high. At the same time, the cost of commissions depends on the workload in the BTC network, it is enough to recall the last autumn and what were the huge commissions.
Not true. The price currently is very high (compared to 2015, 2016, etc.) but the fees are considered low by many, OP included; while in Dec 2018 when the price was only 2x higher than today the fees were aproximately 1000x higher. So the fees are high whenever volatility is high and bitcoin changes hands quickly (and blockchain cannot accomodate all transactions), not when the price is relatively high.
