The choice of coin is the top most priority which will determine your networth in the future like i personally believe btc is best suitable for me considering all the factors like security,fees and profits if i look at both the prospective of payment processing decentralised crypto giving freedom of funds and long term financial asset which will give me profits in long run.

But the problem with people is they don't tend to understand the crypto market and see it as tool to become rich in short span of time which is why many get attracted towards these fake altcoins which only make big promises and those who don't have knowledge and just want profits blindly get trapped in this circle and face difficulties later on.If you have invested $1000 only in bitcoin 5-6 years back you would have lot of funds now but people want shortcut and crypto market have so many such coins that will make millionaires but there is catch in this and that is only the owners of these shitcoins and whales become millionaire not investors.

Make the right choice with your knowledge and give it some time and you will reach your desired goal but you need to work for that and it will come with time and experience only.
