/*

RocketV1 - is an opportunity for you to multiply your capital at times. 
After the start of trading, as soon as the capitalization is 30 ETH, 
we make the coin liquidity lock by 85% (so that 15% of the capitalization is given for sale). 
Thus, we will go to the accumulation of investors and the growth of prices.

RocketV2 - After the results of our first launch version, our developers will complete
this version and we will transfer all assets multiplied by 2 to this version. 
In this version, everyone who keeps our coin gets 20% reflected from the sale of EACH COIN.
There will be many interesting things - stay with us!
