What is your reasoning on the future's contracts?
Discussion
It’s simple leverage on a potentially parabolic asset. The 40% would have to cover any drops so you could ride out the margin calls so allocate for a short term deep price drop. There is no manipulation in the futures as they are “cash priced” based on the spot market.
I would argue that there is manipulation because the spot price is easily moved around and often is especially as it relates to the closing dates on futures contracts.
