I remember the crypto market in 2017, and then I lost more than I earned due to my inexperience, but today I have already known what to do. To my mind,
for beginners, the best choice would be to wait for a rollback of bitcoin to the 6k level and then buy long and make your profit. Good luck

Your hopes for bitcoin at the $ 6K level may be difficult to materialize this year, now that it is already at the price of $ 18K it will take a long time to reach what you want. In fact, bitcoin is now in a period of increase and the possibility of going down could happen but not that far, because bitcoin will also increase again if there is a decline. remember this is the period when bitcoin will continue to increase, so take this opportunity so you can enjoy it too.
