So with the current peak on Bitcon, Ethereum (and nearly all of my alt coins) is it wise to:
1) Take out the profit to either bank or reinvest when there is another dip
2) HODL in the hope that it keeps rising and rising
We don't trading in a linear manner. I hope you have a certain level you want the trade to reach before selling it and getting another. Even though you don't have a target, sell when you think that the market will start turning backward to avoid losing your gain. Although we don't always know when the market will turn bearish but you'll have to time the market so you can get the signal from when price will turn bearish or bullish.
