If an altcoin can rise from $1 to $40 in a bull market, don't think about it, the first $1 to $5-7 is still very smooth. Then it is basically 2-10 US dollars repeatedly oscillating for three or five months, or even more than half a year, and some currencies do not rule out inserting the pin again to around a few points, and then it may soar from 7 US dollars to 40 US dollars in the last few weeks, and then the bull market ends.
