Ans:
You can get maximum exposure to Bitcoins in 3 ways.
Use an exchange: In this way, individuals invest for long terms who buy and hold Bitcoins till they get the best price. But, the exchange charges a fee, poor customer support, no regulatory mechanism, and possibly unreliable engines and servers to deal with.
Bitcoin Derivative Trading: You can use this method with a Contract of Differences (CFDs). You speculate on the Bitcoin price at the close of trading by paying the price difference compared to the opening of the trading. You do not own any Bitcoins. But, you can hedge your derivatives to reduce risks. The market is vast, and Bitcoins sell fast. So, you can put in a nominal margin or deposit and leverage your derivatives. True, it is extremely risky. But you can get high returns too!
Crypto 10 Index: You can trade Bitcoins through the Crypto 10 index platform that allows you exposure to 10 cryptocurrencies in a single trade through the mirroring or index tracking of the crypto’s market price.
