I am growing my bitcoins with the help of signature campaign and trading as I don't have an habit of spending them so whatever I get from signature campaign I try to save them and once I reach to a satisfactory capital I start investing that in different altcoins which helps me in growing my bitcoins faster.
yes that is very good strategy, you just need to keep the strategy continue. to me signature campaign is really a good way of making money no doubt about it, but i think from trading we can really get a good profit, that we cannot imaging from signature campaign, although trading is also a good way of making bitcoin but it is one of the most risky way of making money.
