Top secret?
Buy and dont tell, keep holding until you hit the price you want it to hit
People bought bitcoin when it was 0.15 cents and then sold all that they had when it hit $3 because they thought it wouldnt go any higher
People sold nearly all their ethereum when the price went from $8 to $25 thinking it couldnt possibly go any higher than it already had
these coins are in their beginning stages, just buy on the dips and keep holding.
Sell Ethereum when it hits $1000 a coin and sell ripple when its above $3
True advice , since the blockchain is in the early stage. But also to be mentioned, be careful what you choose. From 10000 cryptos out ther 9990 will fail.
