I don't think they put a lot of money into shitcoin. That's what they expect. Taking a risk on shitcoin with small money to get a bigger profit. But if your friends dare to put most of their money into shitcoin, I'm sure they are reckless people.
Shitcoin is only for the short term. Not to be held in the long term. The longer you hold shitcoin, the greater the risk of losing it. Unlike Bitcoin which has proven its history. This is just a matter of understanding and principle. Some people may think too hard because of the small capital they have and the inability to hold it in the long term.
Coin selection before investing in DCA investment method is very important for any investor. Now if we choose one of the worst coin to invest in and invest in that coin consistently for a long period of time, we will never get success from that investment. First of all we have to focus on coin selection, when we can select the right coin then we have to make sure which method we will invest in. For example, I first considered Bitcoin as an acceptable coin to invest in and then tried to consistently invest in this coin. I have maintained my investment for several years and will continue to do so in the future.
The only coin that should come into the mind of any investor when it comes to coin selection concerning the DCA method is Bitcoin, some investors might want to buy some Alts they feel have potential and DCA with but they're wrong cause you don't DCA using other coins but Bitcoin infact most of those other coins got short-term goals whereas Bitcoin is for long-term investment purpose and that's why it's best for the DCA method. The worst thing an investor would do to their portfolio is to buy and hodl a shitcoin then implement the DCA method on it, that's something the investor would so much regret and might even get depressed cause you'll watch it dumping rapidly at some point. This is something I've experimented in the past, I've held several shitcoins topped up after several intervals and regret was the case so I'm talking out of experience, investors should only buy Bitcoin, hodl Bitcoin, DCA with Bitcoin for investment purposes.
