Many predicts bitcoin will reach 100K, 160K even 200K and more. but no one say what happen then? what happen when reach for example 100K? will be stable, fall to zero, continue with correction or raise more? what is your suggestion

Fall to zero?? This is so a funny statement.. Yeah I know you are a newbie but don't act like real newbie, you should learn about bitcoin first before you ask something like "nonsense"
If Bitcoin reach 100K even more, people who buy it in the past or now will gain big profits.. MONEY.
