Game currency contract is a kind of rivals, belongs to a typical zero-sum game (namely side win, the other party is lost), skill and luck alone, it's hard to beat exchange and the market, to keep the victory for a long time, we need to adopt more sophisticated trading strategies, such as options,

For example, the currency present price is $19000
1, if you use $200 to open more than 20 times leverage do
2, at the same time open two options in BitOffer hedge (cost $40)

First, when the currency rose $950, or 5%
1, 20 times the leverage to do much, profit 100%, that is, earning $200
2, puts the loss of the principal, that is, $40
3200-40=$160 (net)

Second, as the currency fell $950, that is, a 5% drop
1, 20 times the leverage to do much, blowing up contract, loss of $200
2, puts profit $1900, options cost $40
3190-200-40=$1660 (net)

Only in this way, can we ensure that play when contract keep winning,
