I will invest on any of these coins instead of new projects, they have failed me too many times and I don't want to keep doing that, time to move on to old and top altcoins, they are dependable than new coins that only aim on cashing out
Investing in top coins doesnt mean of sure money. Its just that compared to new coins, well established coins are less risky and you have a high chance to profit if you follow the right strategy and mindet of an investor.
What important is you know how to do a research before investing because even old coins has risk.
Cryptocurrencies trading is somehow complicated investing in top 10 coins in coinmarket is not a guarantee of profit making I agreed with you on researching the market sentiments or behavior is the way out to making huge profits a newbie should just pick few coins make research on them and buy at low sell at high.
