I think it's still a good time to buy Bitcoin. But please focus on the long term and don't be fooled by violent fluctuations of the market. Keep holding and never do panic sell!
Buying is a good way but depends on your ability unless you buy it when it is cheap, because you can hold it until the price goes up to your desired target. and besides that you can follow the signature campaign by posting in this forum and you will be paid bitcoin per week
