A very cautious investor can buy on an exchange and then store the bitcoin code off the site or even on a piece of paper — that's what the Winklevoss twins and bitcoin early adopters have done, going so far as to cut up their code into pieces and store it in a vault using a system that only they understand to put the actual bitcoin code back together.

Here’s what I started with a little over a month ago. I put in ~$500 AUD for 0.0572btc. Bitcoin was around $8000 AUD at the time. The 0.0139 is the 24% payout i’ve received since then and is currently worth $310 AUD with BTC sitting at $22600 AUD. This payout will continue until it reaches around 140% and the lending contract expires. It’s recommended to take out your initial investment as soon as you can (about 3 months) and then keep lending out the money that’s leftover and grow it from there for free essentially.
Cryptocurrencies have attracted the attention of several investors all over the world. But in general, institutions did not participate in the market. Back in August, the Intercontinental Exchange (ICE), which operates an important number of regulated exchanges all over the world, announced its intention to launch a new institutional-grade crypto platform known as Bakkt.
Visa processes on average 1,700 transactions per second with the capability of up to 24,000 per second. In comparison, Bitcoin (BTC) capacity is 7 transactions per second. It appears Bitcoin is not scalable. Maybe Eos (EOS) with a capability of 50,000 transactions per second is more long term viable. Possible EOS and RIPPLE are worthy of small bets with potential of 1000X return on original investment due to scalability.
While futures products still carry unique and often significant risks, they can potentially provide a more regulated and stable environment to provide some exposure to bitcoin as a commodity as well. You should carefully consider whether trading in bitcoin futures is appropriate for you in light of your experience, objectives, financial resources, and other relevant circumstances.
