and price of that coin will be minimum of 50k. 
How many coins will be issued? Just 1 (one)?Then it's a bit weird to claim price of the coin will reach 50K and few people will assume you're claiming minimum market cap instead.
You cannot control a coin price like that.
It is only possible if it is a stable coin and the whole market trusts you.
Even if you have enough reserves to peg your coin 1:50k USD, the market just may not trust that you have that money and people may pay only a few cents for you coin.
As you already said you have no budget, your coin will probably have no marketcap as well. It will be worth zero.
Unless you are a genius like Satoshi AND you are solving a problem that lots of people are trying long ago (such as bitcoin did, making the first decentralized cryptocurrency). But I think that in this case you would have to know the basics of coding.
