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!
No doubt it is the right time to buy some bitcoins if you can because the price is decreasing day by day and I think that before Christmas the price will be less than 10k. So if you have decided to invest in crypto then bitcoin is the right choice and it is the right time for investment. In the next year you will see bitcoin will worth more than 50k till the end of the year. Dont waste time and buy some bitcoin.
