The only coin that can multiply in price by the end of this year is bitcoin. I do not think price of other coins will surge significantly as compared to bitcoin. Only a few of altcoins like Binance Coin, Houbi, Bittorrent are some altcoins that have high potentiality to grow over time.
Are you new in crypto-world ?? that thoughts lead me also on not earning / missing profits...
very simple example :
i bought tron at 50 sats an sold it it 80 few hours later , made around 0.25 btc profit, but after 2 weeks it rose above 1700 sats .... can you imagin the profit ....
same with stratis : 4000 sold and earned 0.13 btc then , 6 month laterthe price mooned, per stratis it was 0.0015 orso ... can imagine the profit i lost ....
but 2019 is very bad year for alts ... i hope 2020 will be different
