Definitely worth throwing in a few $$$. Bitconnect price proves that. If you bought at $0.11 and then just put in a sell order for $0.22 to double your money, I'd say that has a better then fair chance of doubling your money. Probably not an effective strategy for thousands of dollars, but probably ok for up to a couple hundred dollars.

Lending is soon to disappear and be overtaken by "staking"....which is still lending but is the platforms' attempt to avoid being defined as securities. I believe there is money to be made in these platforms but you need to be very picky about which ones you choose and timing is EVERYTHING. Get in early, get out early, and don't be greedy. DO NOT lend. Just buy coins and sell when price rises...maybe stake depending on their terms.
