Re: Can early investor turns their small investment into millions?
You know how much difficult it could be holding any other coins than Bitcoin, at some point Bitcoin is the coin that have the holding potential compared to other coins, hence most times it can be very difficult for anyone to buy and hold other coins other than Bitcoin perhaps it can can also be very difficult to identify a good project since majority of them can just merely be scam project such as pump and dump where those that bought with the intention of holding will run at loss, altcoins can be very risky the reason why it is most advisable to deal with only an amount one can afford to lose.
If you compare altcoins and Bitcoin, no doubt Bitcoin is easier to hold than any other coins. Bitcoin is the most recommended coin for holding although it probably takes a long time if we want to target for big profits. However if we have big capital, it may need few months to earn good profits during the bullrun season. Holding top altcoins will be not so difficult, too. Solana, BNB coin, TON are some top altcoins that have increased significantly during this year. Even if we are still not in the peak of bullrun season, these coins showed great progress in growing their values. Especially BNB coin, this coin has reached a new ATH. This simply indicates that they are not difficult to hold, mate. 
As long as there are many old coins with great potential, I think you don't need to do a big efforts in analyzing new projects. There are too many scams and failed projects if we want to consider new projects. For me, it is like gambling to join new projects now. It is no longer as easy as in the past to get potential new projects.
