Anytime anyone show up in crypto is the right time ! You are never late because opportunity is everywhere in crypto ecosystem. From trading to ICO to even airdrops.
Anyone is never late upto this point. As we know that the market is still new and the marketcap of all the coins have'nt reached yet the trillion dollar value. We are still in fresh and lot's of money will flow into cryptocurrency. We should just get in and never too late until now and wait for us all to be a millionaire someday.
And even if bitcoin reached 1 trillion in market cap that will mean an amount of 60k per bitcoin and while that value is high I still think the price could go way higher than that so to me that person will no longer be an early investor but part of the early majority.
