To be honest, there is no one who can answer your question. There is no guarantee that a certain altcoin will increase and give you a profit in just a year. Choosing popular altcoins will increase your chance to make a profit but it is hard to tell on how long will it take. You just have to be patient for that to happen.
we all know that crypto is full of speculation, no one can guarantee that any coins will increase
even so, there is a reason why something happens, like why coin can be pump. in speculation, we talk about the reason
If you are looking for 2x profit in a year, why do not you go for Bitcoin instead? halving will happen next year, and the price should be increased to maintain the miners.
right now Bitcoin is at $8,000 and it is possible for it to reach $20,000 again after the halving.
Why can you be sure Bitcoin will increase in the future? I do not think this can be repeated in the near future because the current market is still unstable and there are still a lot of big fluctuations going on here. In my opinion you should only expect Bitcoin in the range of $10,000 to $12,000 next year because this is the price that can occur and you can consider investing at $8000 if all goes well.
I do agree, there is no guarantee that history will happen again for the next coming 12 months.
Your expectation is realistic unlike in other prediction which is really hard to achieve since there is no demand increase that happens in bitcoin these days.
Bitcoin increases in the future bcz many good things around. halving, china, pump 40% in short time. that's enough to me
