The instructions on the website/forum aren't that clear to me, I would like to invest in an ico for the first time ever and I need your help.
The instructions are very clear. Read:
https://bitcointalksearch.org/topic/m.19226871https://medium.com/nvo-exchange/how-to-contribute-to-the-nvo-crowdsale-d3e4453e3d7dIt suggests on the website using Exodus as a BTC wallet to send funds to the BTC escrow, but in the forum it says the best thing to use is a paper wallet, and if we do not have access to the private key we lose any tokens sent to us, so firstly if I send from Exodus might I lose my tokens?
1) You don't understand what a paper wallet is.
2) I would not recommend a paper wallet investment (as it's nonsensical). Paper wallets are for cold storage.
3) It does not matter what wallet you are using as
long as you have the private key to the address that you're sending from. This means that online wallets, exchanges and similar won't work. A list of supported wallets can be found in the post that I have linked above.
when sending BTC, in instructions it clearly states that "when using 2 different btc addresses, NVOT will be send to each other according to the deposit" - but I can enter only 1 BTC address, so how does that exactly work?
It does not matter which BTC address you put into the dashboard unless you're investing with altcoins. Therefore, you could invest Bitcoin without even registering on the website. I recommend investing from the same address multiple times rather than multiple addresses as you would have to keep track of multiple private keys.
So. I have a jaxx wallet. There is a bitcoin address and its private key. So can I just copy the address from there and submit it to the nvo.io as a personal bitcoin address? And also can I sent bitcoins from that jaxx wallets very same bitcoin address to the nvo.io crowdsale?
Yes and yes.
Another question. There are two bitcoin addresses in jaxx wallet. For some reason. What if I submit one of those address to the nvo.io as a personal bitcoin address and sent the bitcoin from another bitcoin address in the jaxx wallet. Is there any promblem? I guess no. I hold the private keys of both of those addresses in the jaxx wallet.
It does not matter if you own the private key to the other address as well. You would get tokens on that other address, and would need to import it's private key into counterwallet to see the tokens (a guide will be published for this later).
