Hi

I have less than 1 ETH to my name right now so I've been disappointed to have waisted nearly 4 bucks on 2 attempts to send 0.1 ETH as shown in the TX history for my wallet here: https://etherscan.io/address/0x1a841067196cd675e78f349fefc3ae0050f71ca1

The first time, I set the gas limit high, to 200k and the gas price to 50 gwei as per the instructions on http://www.centra.tech/token-sale/index.html. Then the second time, I set it lower because there's plenty of ETH going through at default gas limits (https://etherscan.io/address/0xbdb45d02d8ef8dc5e59aa58b26b99a4af3806baa), but both TXs were cancelled with 'Warning! Error encountered during contract execution [Bad instruction]'

I'm minded not to try again because I'm waisting funds, unless maybe someone could advise me why both my TXs failed please? I've not encountered such errors before?

Also, is there any truth to the rumous that I'll get more CTR tokens if I just buy them now at one of the exchanges where they are already listed? https://coinmarketcap.com/assets/centra/#markets The Centra website doesn't disclose how many tokens you get for your ETH?

Thanks
