It's only sustainable because of the high demand and the still relatively low market cap. I think we can go to 1B market cap, so that's approximately 4x from here. After that I'm not sure that this can still grow, depends on some factors, whether it will be added to DeFi apps etc.
I'd be very cautios with the token at this point. The price is still high, but it may drop any day now. The supply is increasing by 20+% daily, so this probably won't keep rising for much longer.
So then spread it in all your networks - let the pump continue :)
