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
In my opinion the #1 is better option. If you want to hold on, you have to wait a long time to get big profits. In this case, if the market goes down a lot of times, your mind may break and you may sell your btc or others crypto in panic, in which case you will face loss. So #1 better option is to sell your hold crypto when the market is pumped and save your money in bank and buy it again when it is down.
