If a Coin or a Cryptocurrency Project that has been launched and it is not increasing in value in the bull market while others are increasing tremendously, I advise you not to invest in that coin because if invest in it and it's not increase in value now till the bear market again then when do you think the coin will increase for you to make a profit. Investment is all about calculation and wisdom and just throwing your money in the ocean and thinking that one day you will make when the water rise. Investing in altcoins is a very good idea and decision but invest wisely and not to regret later because the coin you invested was nothing but a cymbal drum from the ecosystem to make noise for recognition and the developers of such coins are not to make you benefits from them but for them to make money or profit from you as you invest.
You can't breathe under water. You can't jump to space. You can't fall from 1000 feet without anything and fall to ground at full speed without hurting yourself. These are equally as "helpful" as what OP has started

All jokes aside, thinking that a coin will go up in value during bull run is the hardest part, because you may think that it will, but how would you know?
Maybe you are right and it will, or maybe you are wrong and it won't. I think the best way would be sticking with bitcoin. I know this is altcoin discussions, so stating that bitcoin is the best one is not the way to go, but I feel like that's going to be something that will take a bit of time and should not be something that will be all that easy to be fair.
