The legit projects may be waiting for the right time to enter so that is the reason we only saw scam projects in 2018.If the prices of cryptos increases then we will see the legit projects again or we need to wait until it happening.
I do believe a legit project will never bother about timing. I mean to say when you are having confident on your concepts and executing the plan then probably you will never wait for the right time to arrive but you will make any time as your perfect time for achieving your own success.
But, it must be a humiliating fact that we had many scam projects in 2018. Still that must be the mistake of all of us. Yes, we did not do our enough researches to find them out to avoid them. We supported them by some of possible means like participating in their campaigns and contributing into their ICO kind of ways. That is the reason, more scam people started their own attempts which resulted in making ICO industry as no more attractive enough for investors.
