I feel the total should be there on the index page so that everyone knows how much others are interested in this venture. The value should be in BTC as won't be having USD at the start.
The total raised in each currency is shown at the top of the website. The total raised overall does not exist yet as a feature. You can calculate it yourself for the time being.
I am new to these ICO's and Crowdsales. From what I read on this thread. Sending BTC from coinbase doesn't work? So does that mean I should buy BTC on Coinbase but then send BTC to a BTC Wallet and use the BTC address from that wallet to use for the crowdsale? Which is the best wallet you recommend?
Correct. If you send from Coinbase it is likely that you will lose your money.
On this link you can find my guide on investing and a list of possible wallets. I would personally recommend Electrum.
Also I havent been able to find out how much I need to send to crowdsale? Is there a minimum or a set amount?
There is no minimum, but I would not recommend sending less than 0.01 BTC.
