Bitcoin sounds scary at first but you possibly thought when you were a child that the times tables were too tough to learn but you did it. This is much easier. You download a bitcoin wallet to your phone and then you go to a coin exchange, buy bitcoin with your bank card then send it to your wallet on the phone. Coinbase is one such place, its in usa, there are those which service europe if that one doesn't.
Thats it, dl the wallet, takes a few minutes. Buy coin and send to the wallet, takes an hour or so to verify. Then you can buy from those great sources that only or mostly accept BTC.
To send it you find the receiving address and enter it in the wallet. You are told by then how much btc it will be so you enter that. It may have a lot of zeros after the decimal. $100 in btc looks like 0.0000114 so you have to make sure you copy and paste and double check. Its easy to leave out a zero if you do it by hand. Then it will suggest a miners fee, you click ok and then click send.
