You have hope when investing in Altcoins, of course you have to look at the types of Altcoins, founders, teams, developments in the crypto market and so on, investing in Altcoins takes a long process for you to understand and get profits, in my opinion if you are a beginner just do long-term investments in Bitcoin & Ethreum, it's safer for you.
Without a doubt, the long term investments in well known top list coins are the safest and most rewarding but time consuming.
While this "sentiment" might be good for some investors, most people come in crypto for easy and quick gains and not time-consuming ones. This does not mean that they are bad, but just that their mindset is different and possibly they are in a money crunch and trying some risky moves. For them the downward spiral begins with buying a shitcoin and then watching it go down until it never comes back up.
My honest opinion is that dont try to get into crypto if you are in for short term gains, unless if you have insider information about advisors dumping or something else. Get in to stay for the long and get in for bitcoin.
