I think that is the right decision for you to make. because I also have the same thoughts as you that bitcoin will not increase in the near future. so we have to take advantage of the current altcoin market conditions to be able to increase the assets we own through altcoins.and don't forget to do research before buying altcoins.
Only if OP is ready to risk losing all his money I think it's a good decision if OP wants some money that could change his life. This is the bearish season so I think we can accumulate some potential altcoins. If you want to gamble then we can invest in shitcoins, aka meme coins. But I don't recommend it. It is better to invest in some altcoins that you believe will gain a large market in the future. However, you must still monitor your coins because none of the altcoins are as safe as Bitcoin in storing the value of your money.
Determining which altcoin will do well in the future will certainly not be easy because of the volatile market conditions and the risk involved in investing. In bearish season altcoin accumulation trend can be somewhat positive but if you are stuck in the selection process, chances of capital loss increase. But if the selection process is perfected it is possible to get double or triple profit which is short time interval.
