Yes OG coin can do x5, x100 very easily but very few people took advantage of them at entry and Satoshi level. Many of us are new to the Crypto industry and wants to position ourselves well. Gem are new token just coming to the market unlike OGs which has been in the market for some years and already established a circle and used for trading. Gems comes cheap to the market compared to OGs.
You need to position ourselves, you need to be able to identify the token that will go far. Solana was $1+ in January 2021 and now it's over $140. You also need to be able to determine which token or coin to hold on to and which one to trade off. You need to see a project that does not have value, just coming out and been able to project into it's future. Matics is also a good project still cheap as of now though it comes in billion but it's a decentralized network on another platform.
If you can discover something like this and enter into them early enough, means you have just discovered and entered into a gem. The overall future impact and price action in the future will tell you if you have found a gem or not. Look out for projects that are just coming up and research into them. Buy into them and them hold on. The timing depends on you; it's your investment decisions and your investment attitude comes into play here. Wish you well and don't forget to share with me whatever gem token you just discovered.
