If we are talking about facebook cryptocurrency then the market of facebook is undoubtedly very huge but the market cap of its coin is not doing great. on the other hand if we are talking about IEO's altcoins it is doing very well as compared to FB's Libra. Recently I have also invested in Ieo (Moozicore) according to me this is really a good project for investment. https://tokensale.moozicore.com/
