Based on ur time post, if u bought some coins, it is not late hahahahah. So at now 3. April. 2018, it is late to take part in this party? In fact, many alt coins has fallen below than the ICO prices, u could find some good one.
I don't think it is too late right now. Market predictions indicate the price will reach very big value and thinking it we were not that late even now. It is possible to buy bitcoin with what we have or upon our affordability. Lot of people have a thinking that they were late into the bitcoin and the same will make them not to invest anymore even when they have good volume of fiat in hands. Surely such people will feel bad after years looking at the growth it is expected to attain.
