I do not believe in holding any altcoins, they are not not meant for holding just for a quick profit. In order to gain profits from altcoin you just have to buy at there first stage of presales or private sales and sell immediately or few days of the listing, if not the price will automatically dump leaving you with little or non of your capital. The earlier you sell your altcoins the better your chance of making good profits.
Where else, Bitcoin can be bought at any time and any price because it will definitely not run into loss forgetting the volatile nature price must surely bounce back and give good profits to Bitcoin owners only for those who is in for the long run
Investing in altcoins is similar to gambling in that you never know whether you will make a profit or suffer a significant loss. If you're making an investment and you're not sure you'll make a profit, and you've noticed a number of warning signs and red flags that could cause you to lose money, it's best to take note of risk management and abandon such an investment. Since the creation of bitcoin and other cryptocurrencies, no coin has been able to restore its value after being subjected to market instability. So, with bitcoin investment, you can be rest assured that your investment is safer.
I've known btc way back 2017 and my friend introduced this to me, as a beginner, it's really hard to understand everything. The first thing I did was study here in the forum, an endless reading. By the time I was confident enough to invest, my best friend and I started to invest and hold btc and some other coins. So basically you need knowledge first and be sure you are ready to accept the risk of investing in btc or any other coins.
It's great that you were able to learn about bitcoin before investing in it. You don't need to panic when the price is in a downtrend because you know what caused it and are confident that it will return to its previous value after some time. The investment you've already made in other altcoins indicates that you're already gambling with the rest of your money; don't be so sure you'll make a lot of money there; they don't usually last as long in the market as bitcoin does.
