Having such a goal to get x20 is not shameful, but the problem is to correctly identify the object for investment.
Actually it is possible. but it is too risky because we will not know which altcoins that will really rise up more than 20x higher than the current price. Moreover, not all Altcoins are able to survive and then continue reaching the previous All Time High rven in the next bullish era. So, yes, I think that choosing altcoins will be much risky. I personally will prefer to Bitcoin and continue to do DCA if possible. but once again, it will depwnd on the OP conditon and consideration. as long as the OP is able to hold the risk, it may not be a matter for him.
Always have the target price so you wont miss any chance to take profit. Do DCA with a target, dont just do this without knowing when to stop. If BTC hits a good price and its already your target price, better to take profit without any regret. DCA is a good strategy and many are doing that right now because the bull is about to come and they want to be more prepared, BTC is always a good option for long term.
