Retain VALUE -> YFV, destroy YFV -> VALUE

YFV will no longer be supported within the Value DeFi ecosystem. [4th Nov 2020, 03:37:00 GMT+0]

But manipulating the market with low supply becomes easier.
YFV is useless, but whales may pump it for no reasons like YAMv2 (YAMv2 price is higher than YAMv3. YAMv2 is useless, but HUOBI refuses to migrate v2 into v3 and manipulates the price.)

Thus, we should retain VALUE ->YFV for preventing whales (even CEX) from manipulating YFV.
Once YFV moons, we can swap VALUE -> YFV. On the other hand, VALUE moons, YFV holders can do nothing.
