Everyone wants yo earn money for a better future the problem is not all of us are given a chances it is sometimes depends on luck, selecting new altcoins us very risky it can also fall anytime together with your capital, i only suggest most well known altcoins than investing in new one, or better stay in bitcoin and hold it for future because i believe bitcoin will have a better future than today.
If you are unsure better to use known alt coins or, yes staying with bitcoin have a better chance of earnings from this business, though not that huge as how newer coins can offer, if you are lucky and you invested decent amount to a new project that will be hype up the profits is unmeasurable.
Just a matter how good you deal with your research and how willing you are to gamble with risk, all will going to rely on how well you understand the market and how patience you are in sorting and picking the right investment.
Even they already known altcoins can sometimes crash and never recover again. Investing on them is a big risk but if we are willing to face it and we are only using the amounts that we can afford to lose then why not? Although in Bitcoin, it is still not advisable to go all in.
Many have attempted of doing this by selling all what they got but I never knew what happen to others. Some are successful because they are patient enough to hodl despite of a heavy storm but maybe some got scared and sell at a loss. There might be next better altcoins but many of them are only good at the start. Old altcoins that we already knew are still the ones that remain.
