OP would have made a fortune investing on TON at the time the question was asked. I too had invested and was bullish about TON but the recent controversy of one of its founder being arrested in France for not giving the government user info and chats has made TON suffer a bit. In the long struggle of anonymity vs being a slave of the government, many projects have taken the easier path but the Durov brothers have a past of not giving up on government pressure. They left VK rather than providing user info to the Russian government but Telegram is their ultimate product and they have no places to run. I'd just wait and see how thing progress before deciding to invest in TON.
Like the op many of us didn't invest in ton when it was becoming more popular because we thought it was going to be like many layer 1 coins that haven't done well. Ton had nothing special until Notcoin become successful that other tap to earn apps began to build on the ton network. Some other mini games and apps migrated to tom and made it very popular. Ton is going to become one of the projects to be successful in this bull market but instead of investing in ton. You can invest in other projects that was created on the ton Blockchain because they can give you more profits than ton currently although you're placing a big bet by choosing them because you don't know if they'll be successful as ton or other popular projects created on ton has being. One project I think can be good investment is notcoin because it has all its circulating supply already in the market and many people that received airdrops have sold.
