In my opinion, with Bitcoin, you should not prepare anystrategy. Just buying it and holding in the long time. You will get huge profit
Obviously if we're going to find bigger profit we must go for holding for long term but its unpredictable. Whereas in trading we can have as the demand high. Easy profit yet small but sure. Just a matter of how you do it well.
There a lot of strategies to earn the bitcoin and every strategy is applied on the different kinds of the situations of the customer, like if you have couple of weeks than you certainly cannot opt for the holding option. Also the way of doing and why it is being done also matters, because if you want early profits than you have to do the trading and if you want to stay in the market for longer duration with more surety of the profit than you can do the holding.
