Distribution of new coins that are "mined" are dependent on the price of electricity and popularity. Being first means it was the most popular by default, so it had the most diverse group of "miners", all of them. I could make CrapCoinV37 today, with only myself "mining" it, it would be a worthless expense of electricity if it wasn't popular. The price of Bitcoin stays reasonably in equilibrium with the cost of electricity required to "mine", which is substantial. Most importantly, the Coin that has the highest expense to "mine" is the most secure. To attack Bitcoin by out pacing the current miners, it would require millions of dollars in hardware which could just as easily be used to legitimately acquire Bitcoin by mining. However second place is easily attacked, as the case with BCH, the bitcoin attempted fork. Miners are using their hardware to primarily mine Bitcoin, paying for the hardware, then occasionally attacking BCH, to break it's adjustment algorithm.
