With the current market situation now, investing in ICO is not already profitable.
The best strategy is to invest on undervalued coins, we have a lot of that now since bearish times make it happen.
Depending on the investor but we should not loss our confidence, instead we should consider this timing a great buying opportunity.
People always said it's a great time to buy, and I believe it's true since we are in bearish mode many times in the crypto world.
