Do you really look for a long term profit, like the people who had bitcoin in 2014 or are you here trying to get a quick buck with a minimum effort?
If you are asking about the long term holding then you should not be looking after the quick buck with minimum efforts! That one is sarcastic statement when considered together with the long term holding.
Crypto currencies always need time to get evolved within their projects then only big investors get attracted to them. Then only they make investment during the long course of time and thus gradually the prices start rising for such coins. Thats why they need to be held for the long terms and it works surely!
