I cannot express enough that 'Market Cap' means absolutely nothing when it pertains to crypto. Everyone, while researching a new coin to buy, asks how high will this coin reach? When people respond it can never reach over $1 because of its 'Market Cap', please keep in mind that, A, you clearly did no research as Ripple has already exploited this, and, B, 'Market Cap' means nothing when our government has a multi-trillion dollar dept.
Believe in the coin and tech you are investing in, not the market cap, and you will do just fine - Please remeber that is is easier for a coin to go from .4 cent to $40, then it is for a coin to go from $40 to $4,000 (same return on your ROI).
Be smart, do not let others influence your decision.
