Buy coins from the end of first 100 coinmarketcap. They are very cheap and could grow fast if the idea is interesting. LBRY Credits, Melon, Counterparty, iExec, Storj, district0x now only with 10-50 millions cap each - they could be hundreds and you will earn much more comparing buying coins from the first 10.
Good idea and strategy. Did you ever really try to test this? Market cap is always a dangerous game to play. But suppose you are right,,, this strategy still requires a lot of patience. And patience means months instead of weeks. Am I not right? I looked up LBRY and Storj (randomly) and the first is a long time in the making. Storj looks already very profitable, can it make even more?
This is indeed a good thought. However the total marketcap of all cryptos will steadily grow in the next years to come (at least I am conviced about it) and any coin, also if it's already in top 10 can see really huge growth.
