I Think This is best time to buy btc because correction is almost done we can see pump in btc again from monday and Dont be afraid Waren baffy always said when market is oversold then you have to buy altcoin and when market is overbought you have to sold your coin But one thing is for sure buy and hold always gives you gain. I recommend you to buy and hold at any rate.
There is still correction in the price and the trend is downwards. You can wait a little more but it is not guaranteed that in the next few days the price will down more; therefore I think it is the best time for investment in bitcoin. You will never get such a good chance of buying bitcoin. If you are serious about bitcoin investment then take a step to earn money.
