Invest now? or wait for your turn down? I personally wait for my turn to go down to my new investment and sell it up so that I will benefit from my investment. because all people want to get a profit not a loss "trade terms that is with small capital we get a profit that is as big as" that is what is meant by economics, and all that we also how to deal with all that wisely.
Buy cheap and sell high
Well, better to have other investment strategy in addition to that one you mentioned, like if you are regularly investing a percentage amount of
your money, ex. 10% of your monthly income are invested in crypto. So instead of 10%, better to invest half of it just in case there is a continuing upward trend trajectory.
