I could easily make an exchange but there are so many already.
Then why not make a better one
Better how?
What can I do that would be better?
I use a few exchanges already and I don't really see anything I could improve on.
I don't really want to make a clone.
I have a buttload of ideas for you when it comes to exchanges.
Begin off with a decentralized exchange.
You need at least 500 people to be working on the exchange, keep 50 at first, increase them as time passes.
Keep your exchange updated with new things happening every day(crediting forks, having segwit addresses as an option), find an alternative to hot wallets.
Be in a country which won't ever ask for KYC details.
Better fees, better usability. Give users access to private keys(very important).
Don't list shitcoins.
Have the ability to buy and sell bitcoins for cash directly.
Have the best security measures for your exchange. Avoid having an ICO for your exchange. Get capital through other means.
