An interesting strategy. I am of the opinion that you need to buy some coins and keep them until you reach a certain goal, then sell them. This is not necessary to do with bitcoin, you can also use altcoins.
It's how some of my friends do it, they buy some coins and park it and let it sit for awhile and watch the prices, hodling is pretty much the same as this one since it tends to get long-term instead of a short-term stint, if you aren't good or don't want the hassle that trading has then you should probably do this.
Indeed, based on my experience of trading for 5 years in the crypto world, the easiest and safest way is to buy coins that we think are good
and HODL for several years. We have to do our own research and analysis to make sure the coins we buy are good, after buying these coins,
we don't need to do anything. We just let it be stored in our personal wallets for a few years, according to the target we want to set.
So we don't have to bother monitoring prices every day, and usually if we are right in choosing coins for investment. The holding of these
coins should be able to provide a large profit.
