Bitcoin and Eth make up about 60% of my portfolio. Other safe picks for the next bull run that are about 20% of my portfolio Matic which has a special place in my heart, I bought $1000 worth when it was .02 cents back in 2020 and still hold about 50% of it. Also Polkadot, Cosmos, Avalanche. The other 20% I hold are Pivx, Azero, Uni, Metis, Link, Scrt, Kusama, Gala, Algo, Mana, Mana, Loopring, Syscoin Mina, Audio, Illuvium, Magic, Lido, Rocket Pool, Verasity. There's a few. Gaming will be big this cycle also Defi will always be big in the up cycles. Altcoin Buzz on youtube is a good channel to listen to about some of the up and comers. I use twitter also to learn more about the tokens and then use sites like coingecko.com to do reasearch. Just make sure you follow knowledgeable people.
I also got lucky this cycle I had about $500,000 at top of the cycle at blockfi, Celcius and Voyager. I pulled all my money when luna collapsed in early May out of these sites. Two months later all 3 were bankrupt. Mike Alfred on twitter was a big reason why he kept saying they might go under. If you want some good leverage plays on Bitcoin. Buy some miners, I like HUT, Riot, Clsk and Bitf, I've put a lot money into these the last couple of months. Make sure to do your own research. As they say not Financial advice.
