Before making a million that is
So it's simple really. If I buy for example $1,000 of a coin at $0.01 I will get 100,000 coins which I can sell at $1.00 making me $100,000

OR
I can buy $1,000 of a coin at $0.10 I will get 10,000 coins which I can sell at $10 making me $100,000

You see, it's simple

So, which coin I buy?

It's "simple" to say -- much harder to execute. If it were that easy, everyone would be investing in altcoins and becoming millionaires.
How long do you plan on holding the coin you invest in? a year? 6 months? 5 years?
You need to look for a project coin -- something with a good idea, good tech and a good team.
One such token is FLO. FLO is trading for about $0.08 right now. It is the base blockchain for Alexandria, which is a decentralized multimedia platform. That being said, the potential for FLO to hit $1 even with a year or two is very low. Another project with a lot of potential is MUSIC. It is currently trading for about 1.5 cents. It is a decentralized music platform for artists to publish music.
In any event, putting all your money in one coin is a bad investment strategy. I would suggest a safer alternative. Invest in the obvious coins that will double or triple in value over the next year with the majority of your funds (60-75%). Coins like WAVES, OMG, ETH, LTC and the likes. Those coins will make you some money -- for sure. With the remaining 25% invest in a few "long shot" projects. If they flop, you're not out much -- if they take off, you have the profits from both investments.
That's just my two cents -- good luck.
this was good advise, I think we all want the next 100 bagger .. lemme know when you find it
