This recipee could be a thing of the past. Nowdays it may be better to look for opportunities as lots of talent is going into the market. Do you still think of becoming a millionaire by hodling?
Is it validated to make profit over a long period of time, beucase when the last bitcoin is mined its price will be really rocketed, that's what people is really waiting for.
I think that much earlier than that bitcoin will be surpassed by one or other altcoin and that day its value will be very low. Bitcoin is the first, not the best so, future calling.
